Abstract
An analog multiplexer includes inputs and one output. A switching circuit is coupled between each input and the output. Each switching circuit includes an NMOS switching module, having an on state and an off state, and a control module supplied by a first supply voltage and operating to reduce leakage currents of the NMOS switching module when in the off state. The control module further operates to make the first NMOS switching module bidirectional irrespective of voltages present at the input and at the output.
