Abstract
A switch circuit includes a first MOS transistor and a second MOS transistor of a same conductivity type connected in parallel between a first terminal and a second terminal. The first and second MOS transistors have respective gate terminals coupled to the control terminal to receive a control signal to turn the switch circuit on or off where the control signal transitions from a first voltage level to a second voltage level at a slow rate of change. The first MOS transistor has a first threshold voltage and the second MOS transistor has a second threshold voltage where the first threshold voltage is less than the second threshold voltage.
