Novel Distributed Direct Conversion Receiver for UWB Systems
UWB wireless communications
Few methods have been used to achieve wideband characteristics of RF front-end circuits. The first solution is resistive feedback amplifiers and the second is to extend the narrow band technique to wide band using high order band-pass filtering to achieve the required wideband input matching. These two approaches suffer from a lack of full band coverage and low sensitivity, respectively.The described invention deploys a distributed approach to achieve wideband characteristics of the front-end and has the advantage of its distributed architecture providing intrinsic wideband characteristics and consequently less sensitivity to the passive elements of component variation seen in process.
