6. 20. Analog Baseband Implementation of a Wideband Observation Receiver for RF Applications

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Gustaf Svensson; [2016]
   Keywords : observation receiver RF IC analog baseband digital pre-distortion feedback;

   Abstract : During the thesis, a two-staged analog baseband circuit incorporating a passive analog filter and a wideband voltage amplifier were successfully designed, implemented in an IC mask layout in a 65nm CMOS technology, and joined with a previously designed analog front-end design to form a wideband observation receiver. The baseband circuit is capable of receiving an IF bandwidth up to 990MHz produced by the analog front-end using low-side injection. READ MORE
