Replica network for linearizig switched capacitor circuits
Abstract
The present invention relates to a replica network (400) for linearizing switched capacitor circuits. A bridge circuit (406) with a MOSFET resistor (424) disposed in a resistor branch of the bridge circuit is provided. A noninverting terminal of an operational amplifier (408) is connected to a first node (B) of the bridge circuit and an inverting terminal of the operational amplifier is connected to a second note (D) of the bridge circuit. The second node is separated from the first node by another node (C) of the bridge circuit. An output of the operational amplifier (408) is provided to a gate terminal of the MOSFET resistor (424) and to the gate terminal of the MOSFET switch (204) in a switched capacitor circuit, thereby controlling the resistance of the MOSFET switch so that it is independent of the signal voltage. In this manner, the replica network of the present invention linearizes the switched capacitor circuit. In this manner, the replica network of the present invention linearizes the switched capacitor circuit.
