The goal of this experiment is to gain further experience with Cadence’s Spice,
particularly with Schematics, PSpice, the circuit simulator, and Probe. In this experiment
we will do schematic capture using parts libraries, run simulations in PSpice, display results
in Probe, and then analyze the results using material learned in ECE Lab I and last week’s
experiment. The basis for our work will be the bipolar transistor (BJT) amplifier circuits
and the operational amplifier (op-amp). We will solve DC circuits and AC steady state
Also, time dependent analysis will be performed as well as temperature effects.
We will simulate three circuits that were studied in previous experiments. Prepare a
table in Excel which includes two sets of data: DC and AC.
DC values of I
. And the AC values of (AC), I
. Collect your results from the common emitter amplifier circuit in Experiment 1, and
enter them in this table. Clearly indicate DC and AC quantities and their units. Note, I
DC quantity and I
is an AC.
This experiment is intended to expand your knowledge of Cadence’s PSpice, and
Probe, and computer simulation tools which are useful in verifying a circuit analysis and in
“virtual breadboarding.” The PSpice circuit simulator, and its companion graphic analysis
program Probe, are written and distributed by Cadence for PC and UNIX platforms.
PSpice can simulate analog, digital or mixed-mode (analog and digital) circuits. Simulations
can be performed in the time domain (transient analysis) and frequency domain
