General Fundamentals Edition "Transistor Matching Circuit Design"

The necessity of impedance matching. Complex circuit networks can also be simplified.

When amplifying a signal with a transistor, in order to obtain the largest possible signal, it is necessary to pour all the power available from the signal source into the transistor and to direct all the power amplified by the transistor into the load. To efficiently transfer power without waste, it is essential that the input side and the output side are well connected. The component that facilitates this connection is the matching circuit. If we denote the impedance of the receiving side as load impedance Zr and the impedance of the sending side as source impedance Zs, the power supplied to the load is maximized when Zr and Zs are conjugate to each other. This is known as the "Maximum Power Transfer Theorem." [Features] ○ By using Thevenin's theorem and Norton's theorem, complex circuit networks can be simplified. ○ Similarly, on the load side, the input impedance of any circuit network can be equivalently transformed into a single impedance or admittance.
