A multiphase active-R sinusoidal oscillator circuit is presented. The oscillator can produce M signals (M being even or odd) equally spaced in phase. The circuit has low component count, uses grounded resistors and enjoys low active and passive sensitivities. The feasibility of converting the circuit into a voltage controlled multiphase oscillator is studied. Simulation results are included.
