Consider the small signal equivalent circuit of a MOSFET amplifier shown above. The parameters are given to be: R1 = 300 Kohm, R2 = 109 kohm, RD = RL = 5 Kohm, Rsig = 2 kohm, gm = 5.0 mA/V, kn' = 797 uA/V2, W = 56 um, L = 22 um and |VA| = 100 V, If the DC drop across the Gate-Source terminals, VGS = 4.0 V, find the Threshold Voltage (Vt) of the MOSFET (express the result in Volts, for example as 0.8 V )
If the DC drop across the Gate-Source terminals, VGS = 3.7 V, find the Threshold Voltage (Vt) of the MOSFET. Consider the small signal equivalent circuit of a MOSFET amplifier shown above.
