Baseband amplifier circuit

A baseband amplifier circuit, the baseband amplifier circuit comprising:

• at least one single-ended to differential converter arranged to receive at an input thereof a single-ended input signal to be amplified and convert the single-ended input signal into a differential signal to be amplified, and
• at least one amplifier module arranged to receive at a differential input thereof the differential signal to be amplified and to output an amplified differential signal based on the received differential input signal;
• wherein the at least one amplifier module comprises at least one boosted follower amplifier component comprising:
• a first transconductance device arranged to control a first current between a first supply node and a first output node of the boosted follower amplifier component in response to a voltage at an input terminal thereof coupled to a first input node of the boosted follower amplifier component;
• a second transconductance device arranged to control a second current between the first output node of the boosted follower amplifier component and a second supply node in response to a voltage at an input terminal thereof coupled to a second input node of the boosted follower amplifier component;
• a third transconductance device arranged to control a third current between the first supply node and a second output node of the boosted follower amplifier component in response to a voltage at an input terminal thereof coupled to a third input node of the boosted follower amplifier component;
• and
• a fourth transconductance device arranged to control a fourth current between the second output node of the boosted follower amplifier component and the second supply node in response to a voltage at an input terminal thereof coupled to a fourth input node of the boosted follower amplifier component.
