Basic Fundamentals: "Smith Chart"

Basic Fundamentals: "Smith Chart"

You will be able to easily perform complex complex calculations on charts.

Including transmission lines, solving various problems in high-frequency circuits using mathematical formulas becomes quite cumbersome due to complex calculations. However, by using the Smith chart devised by P. H. Smith, it becomes possible to easily perform such complex calculations graphically. With a slide rule, the property that multiplication can be replaced by addition when taking logarithms is utilized, allowing for easy multiplication by simply moving the slide. Similarly, the Smith chart is a convenient tool that uses conformal mapping to simplify high-frequency calculations. 【Features】 ○ When the load impedance Zr is not equal to the line impedance Z0, part of the incident wave returns to the source side as a reflected wave. ○ Standing waves appear on the line due to the interference between the reflected wave and the incident wave. ○ The ratio of the reflected wave to the incident wave is called the voltage reflection coefficient, generally represented by Γ or Γv.

General Fundamentals Edition: "Operation of Nonlinear Circuits"

General Fundamentals Edition: "Operation of Nonlinear Circuits"

The output changes in the form of a line, that is, a straight line, in response to the input.

A linear element, as the name suggests, is one where the output changes in a linear manner, that is, in the form of a straight line, in response to the input. For example, considering a resistor, the current flowing through the resistor is given by Ir = Vr/R = G･Vr, which is a linear function proportional to the voltage across the resistor. Elements that have this kind of input-output relationship are called linear elements. [Points] ○ A capacitor also follows Ic = jωC･Vc, which is again a linear function of Vc. ○ A nonlinear element refers to one where the output characteristics are not a linear function of the input.

General Fundamentals: Large Signal S-Parameter Analysis Method Using S-NAP/Pro

General Fundamentals: Large Signal S-Parameter Analysis Method Using S-NAP/Pro

Create a linear equivalent circuit and perform linear analysis including surrounding elements.

When a large signal is input into a circuit, it is a well-known fact that the S-parameters of the circuit differ from those in the small signal case if there are nonlinear elements present. In S-parameter analysis, the treatment of active devices generally involves creating linear equivalent circuits such as hybrid pi models at the bias point from models like the Gummel-Poon model, and performing linear analysis including surrounding elements. The linear equivalent circuit at the bias point maintains a linear input-output relationship regardless of how distorted the bias point may be, and does not introduce distortion in the output. To investigate the circuit characteristics when a large signal is input or when the bias point lies in a higher-order curve region, it is best to calculate the S-parameters from the input-output ratio of the fundamental wave component while in the state of large signal input. S-NAP-Pro does not have a direct function to obtain large signal S-parameters, but it is possible to achieve this using harmonic balance. [Features] - Create circuits with ports similar to S-parameter analysis - Label the terminals of each port in the circuit For more details, please contact us or download the catalog.

General Foundation Edition "Method for Exchange of Reference Plane for Measured Data"

General Foundation Edition "Method for Exchange of Reference Plane for Measured Data"

Method for exchanging reference planes of measured data using S･NAP-Pro.

When measuring the characteristics of transmission lines, unwanted elements such as connectors and coaxial lines at the connection point between the calibration reference plane of the network analyzer and the device under test may be mixed into the measurement data. Ideally, it would be best to perform calibration at the device under test end as the calibration reference plane of the network analyzer, but in practice, this is often difficult due to the constraints of calibration fixtures. If it is challenging to remove unwanted elements during measurement, it is necessary to eliminate these elements through post-processing to obtain accurate data for the device under test. In many cases, these unwanted elements are connectors or coaxial lines, and if the data for these elements is known, it is possible to remove them using S･NAP-Pro after measurement. [Features] - If the data is known, unwanted elements can be easily subtracted from the measurement data. - The attenuation per unit length can be 'zero' if the length is short. For more details, please contact us or download the catalog.

General Fundamentals Edition "Basics of Node Analysis"

General Fundamentals Edition "Basics of Node Analysis"

It is an algorithm that can automatically create circuit equations for any circuit.

Why can circuit simulators represented by SPICE freely simulate any circuit? In the circuit analysis learned in school, a specific circuit is given, and the analysis procedure is considered while looking at the circuit diagram. There is no concept of 'solving any circuit' here. However, to put it another way, the process of looking at the circuits in a problem set and constructing simultaneous equations can be replaced by programming, which means solving any circuit. The nodal analysis method is an algorithm that can automatically create circuit equations for any circuit based on certain rules. 【Features】 ○ The nodal analysis method establishes nodal equations at each node based on Kirchhoff's law, which states that 'the sum of currents flowing into a point is zero.' ○ A node is considered as a single point representing parts with the same potential. For more details, please contact us or download the catalog.

General Fundamentals Edition "Design Techniques for Low Noise Amplifiers"

General Fundamentals Edition "Design Techniques for Low Noise Amplifiers"

It is possible to minimize the amount of noise generated inside the transistor.

The noise figure of a transistor amplifier is a function of the source impedance connected to the input of the transistor. Generally, the reflection coefficient that represents this impedance is called Γopt, and by matching the input-side impedance (source impedance) to this impedance, the amount of noise generated within the transistor can be minimized. 【Features】 ○ The noise figure of a transistor amplifier is a function of the source impedance connected to the input of the transistor. ○ Generally, the reflection coefficient that represents this impedance is called Γopt. ○ By matching the input-side impedance to this impedance, the amount of noise generated within the transistor can be minimized.

Study of Power Supply Impedance Using Electromagnetic Field Simulator

Study of Power Supply Impedance Using Electromagnetic Field Simulator

Study of power supply impedance using S-NAP/Field

In the power supply and ground pattern shown in Fig. 4, we remove the IC as shown in Fig. 5 and set a port at the IC's power terminal, then simulate the impedance from that port. The power supply terminal (the port section in Fig. 4) is connected to ground. Fig. 5 shows the current distribution at 225 MHz. As shown in Fig. 6, resonance is observed around 240 MHz, and at this frequency, it can be seen that current is already concentrated on the power input terminal side (the left end of the pattern). 【Features】 ○ Fig. 6 shows the impedance characteristics from 10 MHz to 500 MHz. ○ As is clear from the Smith chart, it demonstrates the characteristics of a transmission line with a short-circuited end. ○ The impedance reaches its maximum around 240 MHz, indicating that resonance occurs at this frequency (λ/4 resonance of the short-circuited stub). For more details, please contact us or download the catalog.
