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:

Furthermore, if a filter precedes the LNA (very common), the filter must be terminated properly to operate with low insertion loss. How about simply terminating the input gate with a resistor equal to Rs? If the capacitance of the gate is low, the input impedance will be ... job shops leeds
