Hi ,
I would like to pass/stop 20V (2MHz)switching signal using 5V in cadence. as shown below with stand alone switch and its application to buck converter in two way switch.
5V control is selectable: it should enable one path at time if we select 5V and other when 0V is applied or any other scheme can be suggested.highvolcontrol.png

Thanks

To control voltages greater than 5V you will need a MOSFET that has a power supply voltage also greater than 5V.
Don't know of any way to control a voltage higher than your supply voltage.
