Consideration of Oscillation Conditions in Self-Excited Oscillator Circuits Related to Microwave Circuits
It can be confirmed that each spectrum is almost consistent in terms of levels.
The oscillation condition of a self-excited oscillation circuit, for example in the circuit shown in Fig. 1, can be expressed as (1) by considering the impedances on the left and right sides from the virtual cutting plane a-a', denoted as Za and Zb. This oscillation condition is satisfied at any cutting plane. However, since the parameters of the transistor asymptotically approach matching as the oscillation grows, it is difficult to confirm the establishment of this matching condition using small-signal S parameters. Therefore, we use the harmonic balance technique of self-excited oscillation to simulate the steady-state oscillation condition and verify the oscillation condition in (1). 【Features】 ○ The oscillation condition is satisfied at any cutting plane. ○ We simulate the steady-state oscillation condition using the harmonic balance technique of self-excited oscillation and confirm the oscillation condition in (1).
