Title: High frequency impedance matching circuit
Inventor: KURIYAMA NOBORU
IPC: C23F4/00
Filed: 1991-03-28
Abstract: PURPOSE:To stabilize a control operation in a high frequency impedance matching circuit. CONSTITUTION:Since a control signal to control serial/parallel variable capacitors 32 and 33 is divided with the output voltage of a high frequency source 1 by providing dividers 73 and 83, constant control velocity can be obtained without being affected by the level of outputted power from the high frequency source 1. On the other hand, since the control changing amount of the serial variable capacitor 32 is corrected by a correcting voltage signal from a correcting circuit 51 corresponding to the capacity value of the capacitor 32 by a multiplier 74 although the control changing amount is changed by the capacity value, the constant control velocity can be obtained at all times and the system can be stabilized. Thus, since the control velocity is fixed even when the output capacity of the high frequency source is changed, the impedance matching circuit with versatility can be provided.
