Abstract
The de-Qing loss and phase imbalance caused by the inherent capacitance of a switched resistance, such as a MOSFET with a resistor, can be reduced by using a shunting switch across the resistor that is in series with the resistor's switch. The shunting switch shorts across the resistor when the resistor's switch is open and in reference mode, thereby significantly reducing the resistance in series with the inherent capacitance of the open resistor's switch.
