Abstract
The present invention is directed to electrical circuits. More specifically, an embodiment of the present invention provides a variable impedance module with a first capacitor coupled to a first input terminal and the second capacitor coupled to a second input terminal. A diode bridge is connected between the input capacitors. The anodes of the top diodes are connected to a supply through a resistor, and the cathodes of the lower diodes are connected to a high-impedance current source. A third capacitor is connected between these two nodes.
