How to use frequency-domain simulations to analyze loop gain and evaluate the stability of your amplifier circuit. We need a way to determine whether a circuit is sufficiently stable—in other words, stable enough to ensure that the circuit will perform properly despite part-to-part variations and environmental or operational conditions that affect the characteristics of the open-loop gain or the feedback network. There is where gain margin and phase margin come into play.

In the last installment, we built the hardware to control an AC waveform with a TRIAC as the first step in a DIY solder reflow oven. This tutorial continues the project by showing you how to set up the low-level hardware to measure temperature, read the zero-cross detector, drive the TRIAC, and print to the serial terminal using a USART.
