Design of fractional-order multiphase sinusoidal oscillators

摘要

Multiphase Sinusoidal Oscillator schemes constructed from integer and fractional-order low-pass filters, are introduced in this paper. The filter configurations are realized using Operational Amplifiers as active elements. The design has the advantage that it is unaffected by the mismatch in the gains of individual blocks. The operation of the proposed oscillator has been evaluated through simulation and experimental results.
