New MMSIM 12.1: How to Set up Transient and Harmonic Balance Analyses with Crystal Oscillators

Preview of Coming Attractions! Here's a new method that will save you simulation time in MMSIM12.1. (Be sure to use IC615 ISR14 or later to see the new MMSIM12.1 features in the GUI.) Here is the method that I use to set up the transient and harmonic balance analyses with crystal oscillators. First, let's look at the schematic. Below is a standard Pierce CMOS 10MHz oscillator. The crystal motional equivalent circuit is shown in the figure below. I will show the junction of the cap and inductor...(read more)
