Additional end-of-chapter problems for Chapter 1 – Introduction to CMOS Design CMOS: Circuit Design, Layout, and Simulation A1.1 Using a SPICE operating point anaysis (.op) simulate the operation of the circuit seen below. Compare your hand calculated values for the node voltages to the SPICE simulation results. What happens to the simulation results if we change the resistor values from 1MEG (10 6 ) ohms to 1M (1 milli or 10 -3 ) ohms? Note that some SPICE simulators are “smart enough” to recognize that 1M is likely a megaohm resistor and therefore interpret 1M as 1MEG (but be careful!) A1.2 Repeat problem A1.1 using a transient analysis (.tran). A1.3 Show, using equations, that the time it takes to reach 1 V (half of the input pulse amplitude) after the input pulse transitions from 0 to 2 V is given by 0.7 RC . Verify this with a SPICE transient simulation. A1.4 Derive transfer functions for the magnitude and phase responses of the following circuit. Using these equations sketch Bode responses (log-log plots). Use SPICE analysis to verify your plots and equations. A1.5
