ABSTRACT:
A programmable capacitance circuit including an input node; an output node; and a plurality of capacitance stages. Each of the capacitance stages is coupled to the input node and the output node, and wherein each capacitance stage is configured to be switched into a circuit path between the input node and the output node. Each of the capacitance stages includes a capacitor, and a control transistor having a gate capacitance in series with the capacitor, wherein the gate capacitance is configured to be added to the capacitance of the capacitor between the input node and the output node.
