a) How is it possible to fabricate both nMOS and pMOS devices on a single substrate?
b) The figure below shows the circuit of a simple cMOS inverter. Initially VIn is set to 0 volts, explain what happens to the 2 transistors and the voltage at "Out" as the voltage pn VIn is increased.
as long as vin is increased effect is explained and also shown by graph.and also for frst qsn the mentioned process in n well fabrication although the famous one is twin tub process only.

Assume the inverter in Figure 1 has a swtching threshold voltage, VM 0.9 V and VDD-1.8 v. Use the following transistor parameter; Let (W/Di = 1/0.18, (W/L)2-2/0. 18. Size transistors M3 and M4 such that when Vin is swept from 0 to 1.8, Vout will switch at Vin= 1.1 V and...
A common source amplifier circuit based on a single n-channel MOSFET is shown in Figure 4b. Assume that the transconductance gm-60 mS (equivalent to mA/ V) and drain source resistance, os, is so large it may be neglected. 0) Calculate the open circuit voltage gain Av Yout/ Vis. i) The amplifier has a load of 10 k2. Determine the current gain Va. = 12 V 150k 4k3 Vout Vin 200k GND = 0 V Figure 4b a) State the name...
