Abstract
A circuit including: input and output nodes and first and second feedback nodes; a first input amplifier having an input connected to the input node and an output connected to the first feedback node; a second input amplifier having an input connected to the input node and an output connected to the second feedback node; a capacitor connecting the first feedback node and the second feedback node; an amplifier having an input connected to the first feedback node and an output connected to the output node; a base feedback amplifier with an input connected to the output node and an output connected to the first feedback node; a tunable feedback amplifier with an input connected to the output node and an output connected to the second feedback node; and a tuning circuit for varying a transconductance of the tunable feedback circuit and operational frequency of the peaking amplifier circuit.
