Abstract:
1. A wireless receiver comprising: a mixer configured to receive an input radio frequency (RF) signal, the mixer comprising a plurality of switches; and a balancing circuit configured to receive a supply voltage and a clocking signal and provide a control signal to a switch in the mixer, the balancing circuit comprising a capacitor configured to receive and selectively dissipate charge as a gate voltage along a gate path; and a pair of transistors configured to isolate the switch in the mixer from the capacitor while the capacitor is charging; wherein the control signal causes switching of the switch in the mixer at times in accordance with the clocking signal according to a voltage difference value between a source voltage and the gate voltage, wherein the voltage difference value between the source voltage and the gate voltage is approximately a predetermined voltage value greater than a turn on voltage level of the switch.
