In this paper, we present the design of an ultra-low power impulse radio for an ad-hoc sensor network. This radio is designed to meet the 802.15.4a standard for UWB impulse radio while achieving low power operation by aggressively duty cycling both the transmitter and receiver with nearly the same "on-time". The key advance that enables aggressive receiver duty cycling is a new approach...
This paper describes a dual band low-IF transceiver front-end for the Mobile WiMAX (802.16e) standard. The transceiver is implemented in TSMC 0.18 mum CMOS technology and covers the frequency ranges from 2.3 - 2.7 GHz. The front end transmitter provides an output gain control of 50 dB with an EVM below 3%, where as the receiver achieves gain of 37 dB and a noise figure of 3.7 dB. The components included...
