Abstract
A body control apparatus for an analog switch for minimizing leakage current and keeping PN junctions reverse-biased. The analog switch has first and second switch device clusters coupled between input and output nodes and controlled by a control input, each having a corresponding body junction. The body control apparatus includes body control devices each controlled by one of the input and output nodes for coupling a body junction to the opposite one of the input and output nodes. Each switch device cluster may include a main switch and body devices which keep the body junction of the main switch at a voltage level between the input and output nodes when the analog switch is on. When the analog switch is off, the body control apparatus activates when voltage across the input and output nodes rises to keep the body junctions at desired voltage levels.
