Digital Electronics - Homework First semester 2024-2025 Part 1: Hand Calculation Consider the following inverter circuit: For the CMOS inverter shown, let VDD = 4 V, kn' = 80 μA/V2, kp′ = 60 μA/V2, VTN = 0.6 V, and VTP = −0.6 V. (a) Let (W/L)n = 2 and (W/L)p = 5. Find Vo for VI = 0.9 V and VI = 3.1 VFind VI for Vo = 0.2 V and Vo = 3.8 VFind VI where VI = VoSketch the voltage transfer characteristics indicating the points calculated before (b) Choose values for (W/L)n and (W/L)p to have a symmetric VTC? Show that the VTC is symmetric by calculating Vo for VI = 1 V and VI = 3 V Part 2: Simulation Draw the circuit on LTSpice and use the parts nmos4 and pmos4, with parameters as in Part 1 and connect the body terminal of the NMOS to ground and the body terminal of the PMOS to VDD. a) Verify the results of part 1 : (a) and (b) of the hand calculation b) Perform the simulation for other value of (W/L)n and (W/L)p, What is the effect of increasing (W/L)n on the VTC?
