Analysis of a Digitally Controlled Wien-Bridge Oscillator


Posted on Feb 5, 2014

This application note analyzes the details of a Wien-bridge oscillator, shows how a JFET maintains oscillation, and demonstrates adding a digital potentiometer (digipot), rather than a variable resistor, to improve stability and flexibility..
