Question

In the circuit of Fig. 3.18, assume that $(W/L)_1 = 50/0.5$, $(W/L)_2 = 50/2$, and $I_{D1} = I_{D2} = 0.5$ mA when both devices are in saturation. Recall that $lambda propto 1/L$. (a) Calculate the small-signal voltage gain. (b) Calculate the maximum output voltage swing while both devices are saturated Figure 3.18 CS stage with current-source load.

Step 1

This configuration typically involves a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) operating in the common-source configuration with its load being another MOSFET configured as a constant current source. The first MOSFET (M1) acts as the amplifier, Show more…
