Patent ID: 8364112

Claim:
A converter, comprising: a mixer comprising a first metal-oxide semiconductor field-effect transistor (MOSFET) having a gate, a first conducting terminal coupled to an input of the converter, and a second conducting terminal coupled to an output of the converter; and a mixer driver having a first output coupled to the gate of the first MOSFET, the mixer driver configured to: receive a local-oscillator signal having a first phase and a second phase; drive the first MOSFET off during the first phase of the local-oscillator signal; drive the first MOSFET on for a first period of time in response to a transition from the first phase of the local-oscillator signal to the second phase of the local-oscillator signal; and force the gate of the first MOSFET into a high impedance state for a second period of time during the second phase of the local-oscillator signal and after the expiration of the first period of time.
