ABSTRACT:
An anti-gate leakage programmable capacitor including at least one capacitor having a first terminal coupled to a first node and a second terminal, a second node, and a control circuit which selectively couples the second terminal of the capacitor to the second node or which drives the second terminal to the same voltage as the first node. In one embodiment, the programmable capacitor includes multiple capacitors, an amplifier having an input coupled to the first node and an output, and a switch circuit coupled to the second node, to each second terminal of each capacitor and to the amplifier output. The switch circuit selectively switches each second terminal of each capacitor between the amplifier output and the second node. The switch circuit may include pairs of switches each controlled by a corresponding select signal to selectively switch a corresponding capacitor between the reference node and the output of the amplifier.
