An amplifier includes a differential pair including a pair of input ports and a pair of output ports and a nonlinear load coupled to the differential pair. The pair of output ports is coupled to the pair of input ports to provide negative feedback. The pair of output ports is coupled to the non-linear load to provide positive feedback. A method includes receiving a signal at an input port of an amplifier and processing the signal in the amplifier by coupling negative feedback and positive feedback produced in the amplifier by the signal to the input port.
