Consider the CMOS circuit shown, where the gate voltage V_{G} of the n-MOSEFT is increased from zero, while the gate voltage of the p-MOSFET is kept constant at 3 V. Assume that, for both transistor, the magnitude of the threshold voltage is 1 V and the product of the transconductor parameter and the (W/L) ratio, i.e. the quality μC_{0x}(W/L), is 1mA. V^{-2}.

For small increase in V_{G} beyond IV, which of the following gives the correct description of the region of operation of each MOSFET?

Two identical NMOS transistors M_{1} and M_{2} are connected as shown below. V_{bias} is chosen so that both transistors are in saturation. The equivalent g_{m} of the pair is defined to be at constant V_{out} The equivalent g_{m} of the pair is
