摘要:

A simple circuit comprising an operational amplifier and anRCfeedback network is configured into a resonant circuit. It behaves as a simple harmonic oscillator for small input signals and changes to an anharmonic oscillator when slew limiting occurs. The circuit is analyzed and the theoretical gain is compared to experimental data for the two cases.
