Abstract
A switching circuit a multiplexer includes an NMOS switch module and a PMOS switch module connected in parallel between an input and an output. A first control module powered from a first power supply voltage operates to reduce leakage currents of the NMOS switching module when in the non-conducting state. A second control module powered from a second power supply voltage operates to reduce leakage currents of the PMOS switching module when in the non-conducting state. A voltage selection circuit is configured to deliver a voltage as the second power supply voltage equal to the greater of the first power supply voltage and the voltages present at the input and at the output.
