Abstract
A cascode amplifier includes a first common-source amplifier (CSA) having a first MOST (metal oxide semiconductor transistor) of a first type configured to receive a first input signal and output a first current to a first node; a first common-gate amplifier (CGA) having a second MOST of the first type and configured to receive the first current from the first node and output a second current to a second node in accordance with a first bias voltage; a first source-follower (SF) having a third MOST of a second type configured to receive a second input signal and output a first voltage at the first node; and a load configured to establish a third voltage at a third node in response to the second current through a DC (direct current) path between the second node and the third node.
