Summary:An amplifier circuit includes a gain controller, a first amplifier, and a second amplifier which is coupled in series to the first amplifier, the second amplifier comprising a plurality of amplifying units. The gain controller is configured to receive a desired gain value and provide, based on the received desired gain value, a gain adjust signal to the first amplifier, and activate, based on the received desired gain value, a certain combination of amplifying units of the plurality of amplifying units of the second amplifier, such that a combined gain of the first amplifier and the active amplifying units of the second amplifier corresponds to the received desired gain value.
