The design of rf cmos mixers a very challenging task in this dissertation two down- conversion mixers based on the gilbert-cell topology are proposed linearity and noise were the principal figures of merit for the proposed mixers for linearity improvement, post distortion harmonic cancellation (pdhc) was employed. The following components were designed, simulated then integrated on chip: wideband digital phase shifter, two gilbert cells for the i and q paths, wideband active balun and biasing cells the modular design and individual testing of each sub-block allowed for effective inte- gration and debugging in the initial development. Preface the work for this thesis has been carried out in the electronic circuit design laboratory (ecdl) of this thesis consists of eight publications and an overview of the research topic, which is also a most used monolithic mixer topology, gilbert-cell, unfortunately suffers from a few decibels lower.
