Abstract

See full text

A power amplifier (PA) linearization technique with a wider linearized power range is proposed. Proposed two types of linearizers with cross-coupled PMOS and NMOS configuration. The idea is to use a complimentary device compared with the PA core device, and the behavior of Cgs of the linearizer are also complimentary to the PA itself. In the other words, the overall Cgs of the PA with the linearizer would be constant without leading to non-linear waveform. Both linearizers can effectively compensate not only AMAM but also AMPM. First type of linearizer can be integrated with PA cores, and second type of linearizer can be used in the IMN. Both linearizers have effective IM3 reduction in different corner.
