Title:
Designing Operational Amplifier Oscillator Circuits For Sensor Applications
Name:
AN866
Date:

Author:
Jim Lepkowski
Description:
Operational amplifier (op amp) oscillators can be used to accurately measure resistive and capacitive sensors. Oscillator design can be simplified by using the procedure discussed in this application note. The derivation
of the design equations provides a method to select the passive components and determine the influence of each component on the frequency of oscillation. The procedure will be demonstrated by analyzing two state-variable RC op-amp oscillator circuits.
