a) Using the constant voltage drop (CVD) model, what is the minimum input voltage that can reach the MOS circuitry before a diode turns on, shunting the current to ground? (At this point you can assume R1 = R2 = 0Ω) b) Using the constant voltage drop (CVD) model, what is the maximum input voltage that can reach the MOS circuitry before a diode turns on, shunting the current to the supply (Vdd)? (At this point you can assume R1...

can you do the calculation of the three parts, don’t do the somulation or ads i just need the calculation 3) (a) Consider the following circuit which you might have seen it previously in digital courses as an inverter (NOT) block. In this problem, on the other hand, we would like to treat it as an analog amplifier. Taking channel-length modulation into account ( 0), calculate the small signal gain.

. please help me from a to e Recall the Offset Nulling Circuit that you used to zero out the offset of the LM741 OpAmp in L2002B, shown in Figure 1(a). An external 10 k2 potentiometer was applied across the emitter terminals of the current mirror formed by Q5 and Q6 in Figure 1(b), which can be thought of as making an adjustment to collector currents Ics and Ics such that Ics-Ics exactly A simplified version of that current mirror...
