Hi
I WANT SWITCH A MOSFET WITH A MICRO CONTROLLER PWM WITH 100HZ FREQUENCY OF SWITCHING . .
I WANT ISOLATE AN AREA OF CIRCUIT FROM OTHER AREA WITH MOSFET.
THIS MOSFET PASS 3 MICRO VOLTS IN ON STATE .
MY UC WORK WITH 100MHZ CLOCK.
WHEN MOSFET GO ON STATE WITH MICRO CONTROLLER PWM ,100MHZ NOISE APPEAR ON GATE OF MOSFET. AND INJECTED TO PRECISION SIGNAL.
I NEED A FILTER FOR THIS NOISE FOR REMOVING NOISE FROM GATE .THIS FILTER CAN BE SIMPLE RC FILTER OR OPTOCOUPLER .
PLEASE HELP FOR SOLVE THIS ISSUE.
SINCERELY
