Abstract
In accordance with an embodiment, an adjustable capacitance circuit comprising a first branch comprising plurality of transistors having load paths coupled in series with a first capacitor. A method of operating the adjustable capacitance circuit includes programming a capacitance by selectively turning-on and turning-off ones of the plurality of transistors, wherein the load path of each transistor of the plurality of transistors is resistive when the transistor is on and is capacitive when the transistor is off.
