Pseudo NMOS Inverter (will explain why it's called this way later): Calculate Vo and Ids for Vin = 0, 1, 2, 3, 4 and 5 V for the following inverter. Plot VTC based on these calculations. Device parameters are: for PMOS, Vtp = −1 V, kp = 0.5 mA/V2; for NMOS: Vtn = 1 V, kn = 1 mA/V2.
Design the CS stage for a voltage gain (Av = Vout/Vin) of -4, a power budget (P) of 2 mW, and a voltage drop of 200 mV across Rs. The overdrive voltage of M1 must not exceed 300 mV, and R1+R2 must consume less than 0.1 mW. Use μnCox = 200 μA/V2, VTH = 0.4 V, λ = 0, VDD = 1.8 V and. The coupling capacitors (C) are short circuits at frequencies of interest. (a) Determine Rs1, R1, R2 (b) Determine W/L (c) Determine RD (d) Verify that M1 operates in saturation. If not, why is it?
