A New Current-Mode Multiphase Sinusoidal Oscillator Using Adjoint Op-Amp

Article Preview

Abstract:

In order to get current-mode multiphase sinusoidal oscillator with high frequency, high accuracy, high stability and easy to be integrated, a multiphase sinusoidal oscillator circuit is presented. The oscillator can produce N output-currents (N being even or odd) with equal-amplitude and equal- phase spaced. The circuit uses adjoint Op-Amp, grounded capacitors and enjoys low passive sensitivities. The oscillation condition and frequency for the oscillator can be tuned independently. The simulated results are illustrated.
