Transistor Circuit Modeling for Digital Design
In digital design, other than connectivity, transistors only have a single design decision
(width or k factor), or are part of a standard cell in which case the decision is changed to

ECE 721 - Spr 2012 Quiz 1 Solutions
1.Given a CMOS inverter with Vtn = |Vtp| and Bn = Bp. What is the trip point voltage Vtr
relative to Vdd? (Vin of region C of DC transfer curve).
Since symmetric, Vin = 0.5*Vdd.
0.5*Bn(Vin Vtn)^2 = 0.5*Bp(Vdd Vin - |Vtp
