Abstract
A circuit includes a phase adjustment capacitor (PAC) coupled to a signal path and configured to adjust a phase of a signal on the signal path. A transistor switch device is coupled in series with the PAC to provide a circuit branch parallel with the signal path. The transistor switch device is configured to selectively open or close the circuit branch of the signal path to enable or disable, respectively, the adjustment of the phase of the signal on the signal path via the PAC. A nonlinear capacitance is coupled to a node interconnecting the PAC and the transistor switch device. The nonlinear capacitance is configured to vary inversely proportional with a capacitance of the transistor switch device with respect to the signal on the signal path and to linearize a total capacitance provided by the circuit branch when the circuit branch is open.
