Abstract

A radio frequency amplifier comprises an input amplifier provided with a shunt feedback path for determining the input impedance. A first transconductance amplifier forms part of a series feedback arrangement with a resistor around the amplifier so as to boost the effective value of the resistor. An identical transconductance amplifier is connected to the output of the input amplifier and its output forms the output of the radio frequency amplifier.
