Abstract
In accordance with an embodiment, a switchable capacitance circuit includes a plurality of capacitance-switch cells that each has a first semiconductor switching circuit and a capacitance circuit having a first terminal coupled to the first semiconductor switching circuit. A resistance of the first semiconductor switching circuit of a first switch-capacitance cell of the plurality of capacitance-switch cells is within a first tolerance of a resistance of the first semiconductor switching circuit of a second capacitance-switch cell of the plurality of capacitance-switch cells, and a capacitance of the capacitance circuit of the first capacitance-switch cell is within a second tolerance of a capacitance of the capacitance circuit of the second capacitance-switch cell.
