Input voltage for MOSFET can vary starting from less than a volt to hundred of volts for power MOSFET. Operating frequency of a MOSFET can be order of Gigahertz. For full details you can see datasheet of the MOSFET.
what is the input voltage(AC or DC)? and for which terminal we have to give input?
I think for gate terminal we will give current pulse as input? can you please clarify me
