HIGH LINEARITY PUSH-PULL COMMON-GATE AMPLIFIER

摘要

An amplifier (107, 109) operates to provide a high output impedance at an output (208) through a push stage having a first transistor (M1) of a first transistor type and a pull stage having a second transistor (M2) of a second transistor type that is different from the first transistor type. The first transistor (M1) and the second transistor (M2) are coupled in a common-gate configuration. The first transistor and the second transistor are shorted together via a capacitor (C1) coupled to an input and share a common current path as a push-pull current-reusing common-gate low noise amplifier with a broadband input matching.
