Mosfet small signal parameters
Biasing of MOSFET. *N-channel enhancement mode MOSFET circuit shows the source terminal at ground potential and is common to both the input and output sides of the circuit. *The coupling capacitor acts as an open circuit to d.c. but it allows the signal voltage to be coupled to the gate of the MOSFET. As Ig = 0 in VG is given as,If we assume that all transistors are in saturation and replace the small signal parameters of g m and r ds in terms of their large-signal model equivalents, we achieve Av = vout vid = (K'1ISSW1/L1)1/2 ( 2 + 4)(ISS/2) = 2 2 + 4 K'1W1 ISSL1 1/2 1 I SS Note that the small-signal gain is inversely proportional to the square root of the bias ...
