Abstract
An amplifier for a receiver circuit is disclosed. The amplifier has an input node (V) and an output node (V). It comprises a tunable tank circuit connected to the output node (V), a feedback circuit path connected between the output node (V) and the input node (V), and a tunable capacitor connected between an internal node of the feedback circuit path and a reference-voltage node. A receiver circuit and a communication apparatus is disclosed as well.
