Unformatted text preview: University of California, San Diego Department of Electrical and Computer Engineering ECE65, Fall 2009 Lab 1, Introduction to PSPICE Simulations Note: Each student has to turn in this assignment (treat this as a homework, do not use the lab report format). Due in the lab at your lab section. Attach the simulation circuit and all simulation results to your work. Problem 1: Voltage Divider (Bias Point, DC Sweep, Parametric sweep, plotting) In many occasions we need to bias the circuit components with a voltage that is different than the power supply voltage. Other times we need to feed back a signal proportional to the output signal of one part of the circuit to another part. The voltage divider circuit below is the simplest circuit that does these functions and, therefore, is used extensively in the electronic circuits. 1 2 L i o o- + +- R R R v v i 1) Use PSpice to simulate the above circuit with R 1 = 2 k, R 2 = 2 k, R L = 20 k, and v i = 6 V. Use Bias Point Details option to find the value of= 6 V....
