    This research presents a wideband mmWave receiver front-end that covers the frequency range from 43 to 97 GHz, supporting the operation in the major parts of the V-, E- and W-bands. The front-end incorporates a passive mixer-first topology to achieve high linearity and wideband performance along with an optimum operational instantaneous bandwidth. In addition, it implements the multi-gate gm3 cancellation technique at the IF amplifiers to preserve the linearity and provide gain at the IF section. Image rejection capabilities using a current mode transformer based IF 90o coupler is implemented on chip and demonstrated with measurements. The front-end is fabricated on the Globelfoundries 22nm FD-SOI CMOS process and demonstrates an ultra-wideband performance across the frequency range 43-97 GHz (2.25:1 bandwidth) with image rejection of up to 32 dB, IIP3 of 1.6-5.2 dBm and gain of 15 dB. Furthermore, the measurement results show that the front-end supports high speed modulated signals of up to 6 Gbps 64QAM modulation data.M.S

    La intención de esta tesis es recopilar información desde un punto de vista general sobre los diferentes tipos de componentes utilizados en un receptor de señales a 5 GHz utilizando tecnología CMOS. Se ha realizado una descripción y análisis de cada uno de los componentes que forman el sistema, destacando diferentes tipos de configuraciones, figuras de mérito y otros parámetros. Se muestra una tabla resumen al final de cada sección, comparando algunos diseños que se han ido presentando a lo largo de los años en conferencias internacionales de la IEEE.The intention of this thesis is to gather information from an overview point about the different types of components used in a 5 GHz receiver using CMOS technology. A review of each of the components that form the system has been made, highlighting different types of configurations, figure of merits and parameters.
