Consider the CMOS circuit shown, where the gate voltage VG 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 μC0x(W/L), is 1mA. V-2.
Estimate the output voltage V0 for VG = 1.5 V. [Hint: Use the approximate current voltage equation for each MOSEFT -
