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