Abstract
Certain aspects of the present disclosure provide methods and apparatus for amplifying signals with an amplification circuit. The amplification circuit generally includes a first transistor, an input path coupled between an input node of the amplification circuit and a control input of the first transistor, and a feedforward path coupled between the input node and a feedforward node. In certain aspects, the amplification circuit may also include a first resistive device coupled between the feedforward node and the control input of the first transistor, a biasing circuit coupled to the feedforward node, and a low-impedance path coupled to the feedforward node.
