WebThis high input impedance is controlled by the gate biasing resistive network formed by R1 and R2. Also, the output signal for the enhancement mode common source MOSFET amplifier is inverted because when VG is low the transistor is switched “OFF” and VD (Vout) is high. When VG is high the transistor is switched “ON” and VD (Vout) is low as shown. WebFor a MOSFET the high input resistance is caused by the isolation layer between gate and channel (blue in the picture): The layer is made of SiO 2, which has an extremely high resistance of 10 16 Ω ⋅ m, and is one of the best insulators existing.
