Abstract
A current mode sinusoidal oscillator includes a current amplifier with distinct current input and four output terminals. The amplifier includes a current input terminal X, a first and a second negative current feedback terminals Iand I, along with a positive current output terminal Iand a negative current output terminal I. The oscillator is characterized by a first feedback path that transmits a portion of a current at the first negative current feedback terminal Ito the current input terminal X of the oscillator. Additionally, a second feedback path, interlinking Iand X, comprises a three-stage phase lag network designed to confer a phase shift of negative 180 degrees to the current signal at a frequency of oscillation determined by capacitor and resistor values of the three-stage phase lag network. A load is connected between Iand I, which receives the sinusoidal current at the frequency of oscillation.
