Abstract: A gm-C circuit includes a two-stage common mode control loop to limit the common mode voltage during circuit operation. To prevent latch-up in a cross-coupled differential gm-C type filter, the common mode control loop includes a circuit which provides extra current capability to the common-mode control loop without increasing the quiescent current. This is accomplished by a current boost technique that provides large amounts of current when needed, while running in a low current mode under normal circumstances.

Abstract: Disclosed herein are tunable reactance circuits configured to present a tunable or variable capacitive reactance when energized. The circuits can include a switch configured to be controlled by a gate driver, the gate driver configured to receive a control signal indicating an on-time of the switch; a diode coupled antiparallel to a switch; 5 and one or more capacitors coupled in parallel to the diode. The tunable capacitive reactance can be based on the on-time of the switch and a total capacitance value of the one or more capacitors. The exemplary tunable reactance circuits may be used in wireless power transmitters and/or receivers for efficient power transmission and/or to deliver a particular level of power to a load.
