BODY BIAS COORDINATOR, METHOD OF COORDINATING A BODY BIAS AND SUB-CIRCUIT POWER SUPPLY EMPLOYING THE SAME

摘要

A body bias coordinator is provided for use with a transistor employing a body region. In one example, the body bias coordinator includes a control unit configured to control the transistor and make it operable to provide a virtual supply voltage from a source voltage during activation of the transistor. The body bias coordinator also includes a connection unit coupled to the control unit and configured to connect the body region to the virtual supply voltage during activation of the transistor. In an alternative embodiment, the connection unit is further configured to connect the body region to another voltage during non-activation of the transistor.
