Abstract
A method, algorithm, architecture, circuits, and/or systems for low noise amplification are disclosed. In one embodiment, an amplifier can include an input stage, including a first differential input configured to receive a differential signal, a first current source coupled to the first differential input, a first current load receiving a first bias voltage and coupling the input stage to a first power supply, and a first pair of common mode feedback transistors, coupled to an output of the first current load and configured to limit a current to the first current source. The input stage provides an amplified signal to an additional stage having a structure similar to the input stage, configured to further amplify the amplified signal.
