Question:
Find the output resistance for the active-cascode circuit of Fig. 3.77 excluding resistor R. Assume that all the transistors operate in the active region with dc drain currents of 100 µA. Use the transistor parameters in Table 2.4. Ignore the body effect. Assume W = 10µm, Ldrwn= 0.4µm, and Xd=0.10µm for all transistors. Check your answer with SPICE.
