Gate input resistance

WebDec 31, 2024 · An example of using the MOSFET as a switch. In this circuit arrangement an Enhancement-mode N-channel MOSFET is being used to switch a simple lamp “ON” and “OFF” (could also be an LED). The gate input voltage VGS is taken to an appropriate positive voltage level to turn the device and therefore the lamp load either “ON”, ( VGS = … WebThe circuit input impedance is R s in parallel with the device input impedance. Using a typical Y fs of 5000 μS, the input impedance of a Common Gate Circuit is around 200 Ω. Low input impedance is the major disadvantage of the Common Gate Circuit, because the signal voltage is divided across r s and Z s, (see Fig. 11-22). Output Impedance:
