AC voltage level circuit

Published:2011/6/30 19:47:00 Author:TaoXi | Keyword: AC, voltage level | From:SeekIC

This circuit automatically or manually adjusts the level through a variable capacitor bleeder. Here the bleeder is composed of the varactor D, the capacitance and the resistance. The field effect transistor T1 can be used in the isolation between the signal source and the adjusting loop. The transistor T2 and T3 can be used to make the output circuit to has low resistance value. In order to reduce the waveform distortion when the high-frequency voltage is high, you can connect the circuit of figure (b) after the circuit of figure (a).
