Step 1
These are called the switching thresholds and are given by the points where the VTC intersects with Vout=2.5V (the midpoint between the high and low voltage levels). From the VTC, we can see that the switching thresholds occur at Vin=2V and Vin=3V. Therefore, the Show more…

Question: Consider a resistive load inverter circuit with VDD = 5V, Kn = 20 uA/V^2, Vto = 0.8V, RL = 200 kΩ, and W/L = 2. Calculate the critical voltages (VoL, VoH, Vil, VIH) on the VTC and find the noise margins of the circuit: The noise margin for low signal levels (NML) and the noise margin for high signal noise (NMH): NML = VIL - VoL, NMH = VOH - VIH.
