WebIn the diode connected PMOS, fig.B, Gate and Drain are shorted. Hence V G = V D. And therefore V G D = 0 and V G S = V D S. M2 will always be in saturation as V D S > V G S … WebDec 14, 2024 · I have read that it is possible to use a diode-connected MOSFET as a small-signal resistor with a resistance of 1/gm (ignoring channel length modulation.) Also, the equation for gm is as follows: Note that this equation shows that gm is dependent on Vgs (=Vds for diode connected devices.)
