As proposed by MB-OFDM alliance, the spectrum for UWB communication system ranges from 3.1-to-10.6GHz, which is divided into 14 bands, each of 528MHz bandwidth, and categorized into 5 groups [1]. To meet the stringent fr

in the past few years [1,2]. This paper discusses the integration of a 60GHz CMOS single-chip transmitter and a singlechip receiver using a standard 90nm CMOS technology demonstrating a reliable solution for 60GHz single

and comsumer electronics applications, and its standardization is still in progress. The WPAN standards such as IEEE802.15.4 and 4a do not meet the WBAN requirements such as energy efficiency on the body, scalable QoS, a
