We… WebThe impedance of a resistor stays constant with frequency. For a capacitor, its impedance get smaller and smaller as frequency goes up. If R and C are in series, at 0 frequency the capacitor has infinite impedance (1/jwC = infinity), so it acts like an open circuit (we say a capacitor blocks DC current). The Resistor will have zero current and therefore zero …

How to calculate input impedance for this simple circuit?

WebThe general approach to calculate input impedance (or output impedance) is to inject a small current into the input node (di) and look at the resulting change in voltage of the input node (dv). Or, equivalently, to apply a small voltage (dv) and look at the resulting current (di) from your test voltage source. Then compute (dv/di). Web• Open circuit voltage gain ~ 1 • Input resistance ~ CS Amplifier – We want a large input resistance because the controlled generator is voltage controlled • Output resistance << CS Amplifier – We want a low output resistance to deliver most of the output voltage to the load v in + − v in + − v out + − (g m + g mb) 1 (g m + g mb ... northgate directions
