Analog tips for CircuitMaker

Component values

You can edit component values by double clicking on the value labeling the circuit. You can use the following prefixes:

Prefix Meaning
p pico, 10-12
n nano, 10-9
u &mu, micro, 10-6
m milli, 10-3
k kilo, 103
Meg mega, 106

Do NOT leave a space between the numerical value and the prefix: 1u or 1.0u, not 1 u or 1.0 u.

AC Analysis

AC analysis gives us the plot of Vout vs. frequency. Most times we prefer a logarithmic frequency scale, so we need logarithmically spaced frequency values. In Simulation > Analyses Setup, click on AC Analysis and choose three to five points per octave. This will give us points that are equally spaced on a log frequency scale, three to five points in each factor of two in frequency.

To get a log display, click on the pink sine wave button in the corner of the AC Analysis window during simulation, and choose Log under X grid.
