In the circuit of Fig. 1, assume that all devices operate in saturation. Figure 1: Circuit for problem 1. Determine the operating points of all the devices in the circuit. Assume λ = 0 for all devices. The answers should be in terms of |VTP|, VTN, μnCox, μpCox, R, Vdd & (W/L). What is the transconductance of M1? How does it depend on the device thresholds, μnCox and μpCox? What do you think the practical utility of this circuit is? Determine the minimum Vdd required to ensure that all devices are in saturation.

In the circuit of Fig. 1, assume that all devices operate in saturation.
Figure 1: Circuit for problem 1.

Determine the operating points of all the devices in the circuit. Assume $λ = 0$ for all devices. The answers should be in terms of $| V_{T P} |, V_{T N}, μ_{n} C_{o x}, μ_{p} C_{o x}, R, V_{d d} & (W / L)$ .
What is the transconductance of M1 ? How does it depend on the device thresholds, $μ_{n} C_{o x}$ and $μ_{p} C_{a x}$ ? What do you think the practical utility of this circuit is ?
Determine the minimum Vdd required to ensure that all devices are in saturation.
