Variable Sinusoidal Oscillator
View pageUS Patent:
41248279, Nov 7, 1978
Filed:
Nov 17, 1977
Appl. No.:
5/852322
Inventors:
Dale L. Hileman - Topanga CA
International Classification:
H03B 520
US Classification:
331135
Abstract:
A variable sinusoidal oscillator comprised of an operational amplifier connected in a unity-gain configuration, with a positive-feedback capacitor connected between the output and the noninverting input of the amplifier, and a resistor between the noninverting input and circuit ground, either in the form of an external resistor or simply in the form of the input resistance of the amplifier. A linear attenuator may be connected in the negative-feedback circuit, and a nonlinear attenuator may be connected in tandem with the capacitor, or vice versa.
