4. All the transistors in the circuits shown below have the same values of V[],k’, W/L, and 2. Moreover, 2 is negligibly small. All operate in saturation at Ip =I and IVGsl = 1Vpsi = 1 V. Find the voltages V2, and V4. If |V+1 = 0.5 V and I = 0.1 mA, how large a resistor can be inserted in series with each drain while maintaining saturation? If the current source I requires at least 0.5 V between its terminals to operate properly, what is the largest resistor that can be placed in series with each MOSFET source while ensuring saturated-mode operation of each transistor at Ip = 1? In the latter limiting situation, what do V2 and V4 become? +1V +1V +1.25 V | Q2 世 Q4 -O V₂ OVA I 1 -1.5 V (a) -1.25 V (b)
