In a bypass circuit the top of a capacitor is
WebOct 17, 2005 · Bypassing is the reduction of high frequency current flow in a high impedance path by shunting that path with a bypass, usually a capacitor (in this case, C byp ). Bypassing is used to reduce the noise current on power supply lines. Decoupling is the isolation of two circuits on a common line. WebAug 3, 2024 · For a common cathode circuit, the CCS would have to have a bypass capacitor or there would not be any gain. Also, you can not use a CCS in the cathode circuit, and also a CCS in the plate circuit (at the same time). Perhaps it makes more sense to put the CCS in the plate circuit. The stage will have more gain, and lower distortion than with a ...
