Patent ID: 8718574

Claim:
A local oscillator (LO) module comprising: a local oscillator, biased at a supply voltage, for generating a local oscillator signal having a duty cycle; and a feedback circuit for making an absolute adjustment of the duty cycle of the local oscillator signal in response to a difference between a first voltage signal, representing a voltage level of the local oscillator signal, and a second voltage signal, representing a voltage level of a portion of the supply voltage corresponding to a desired duty cycle for the local oscillator signal, wherein the feedback circuit comprises: first means for determining the first voltage signal; second means for determining the second voltage signal; third means for receiving the first and second voltage signals; fourth means for comparing the first and second voltage signals in response to receiving the first and second voltage signals; fifth means for determining a difference between the first and second voltage signals in response to comparing the first and second voltage signals; sixth means for determining an adjustment signal in response to determining the difference between the first and second voltage signals; and seventh means for generating a control signal in response determining the adjustment signal.
