DIVIDE-BY-THREE QUADRATURE FREQUENCY DIVIDER

摘要

A local oscillator circuit, comprising a timing circuit configured to provide an in phase signal and a quadrature phase signal; a delay circuit configured to delay the in phase signal, thereby producing a delayed in phase signal; and a feedback circuit configured to receive the delayed in-phase and quadrature signals and provide a bias adjustment signal to the delay circuit to control a delay time of the delay circuit.
