MOSFET PARAMETRIC AMPLIFIER

摘要

A circuit (48) includes an input terminal adapted to receive an input voltage (VRF), a MOSFET (16) having its drain terminal (20) and its source terminal (18) connected together, a first switching arrangement (30) configured to be controlled by a first clock signal (phi1) and adapted to selectively couple the gate terminal (22) to the input terminal (12), and a further switching arrangement (40, 34) configured to be controlled by a further clock signal (phi2) in timing relationship with the first clock signal and adapted to selectively couple the source terminal and a first voltage (Vpull) which is capable of pulling carriers out of a channel when the first switching arrangement is not coupling the input terminal to the gate terminal.
