Abstract
The increasing level of integration in CMOS is leading to an increasing number of standards and bands which are implemented in a single handset transceiver. Unsuitably each implemented standard and band requires a dedicated external surface acoustic wave (SAW) band select filter to fulfill the out-of-band blocker requirements mandated by the respective standard. Obviously, this obstructs front end flexibility, increases the handset form factor, bill of materials and cost. This thesis aims to investigate upon the existing designs and develop a fully integrated wide-band receiver without the off-chip SAW filter. The design thus developed will be evaluated per rigorous simulations. The thesis will mainly focus on design of a low power wide-band filter-less LNA complemented by a suitable mixer, compatible with the NB-IOT specification, its linearity, noise performance and power efficiency, for an optimum noise figure, conversion gain and lower intermodulation distortion. Main parameter of interest here is to manage a blocker level of -15dBm while maintaining decent sensitivity, with the minimum achievable inter-modulation distortion, especially the third order.
