Unformatted text preview: Albert Ho ECE 315 Tuesday lab Lab 01 writeup Objective: The purpose of this lab is to familiarize oneself with PSpice, a program that simulates electronic circuits. By using familiar circuits as examples, it serves to show us the basics of using PSpice upon which we will build during the course of the semester. Equipment: Cadence PSD 15.0 PSpice Simulation software Experimental Results: Simple Voltage Divider and DC Bias Point Analysis: The following circuit diagram was assembled in PSpice and shows the simulation results for DC bias point analysis at interesting points. There is a DC voltage source. Figure A: Voltage divider circuit diagram with DC bias point values The voltages across R1 and R2 are as follows: 1 2 1 1 1 V R R R V R + = 1 2 1 2 2 V R R R V R + = RC Low Pass Filter Transient Analysis The following circuit diagram shows a lowpass RC filter. It is being driven by a sinusoidal voltage source of 5 V amplitude and 1 kHz frequency. The circuit elements include a 10 k resistor and a 0.01 F capacitor in series. Figure B: RC low pass filter circuit diagram The voltage and current through the circuit obey the following solutions (with complex magnitudes V o and I o ): t j o e V V = t j o e I I = The magnitudes and phases are computed as follows: ( ) ( ) ( ) RC RC V V o 1 1 2 1 tan 1 + = ( ) ( ) 2 tan 1 1 1 2...
