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 this teardown Tuesday we will take apart an Ikea smart lamp that can be controlled via an external remote.

The OPB9000 is a reflective light sensor from TTElectronics with programmable output and sensitivity levels.
