An energy detector designed in a 0.18μm CMOS technology and intended for a non-coherent impulse-radio UWB receiver is presented in this paper. The proposed circuit exploits the quadratic current characteristic of saturated MOS transistors to square input pulses that cover the whole UWB bandwidth. The integral is computed with a Gm-C architecture connected(More)
In this work, direct injection locking is applied to a ring oscillator topology to design a wideband divide-by-two frequency divider circuit with a locking range covering bands <i>S</i> through <i>K</i><sub>u</sub>, namely input frequencies from 2 to 16 GHz. A thorough analysis is carried out: a behavioral model is developed that allows us to capture the(More)
A fully integrated solution for rejecting the interference caused by Wireless Local Area Network transmissions in the 4.9–5.825-GHz band for ultra-wide-band (UWB) receivers is presented. Front-end prototypes implemented in a low cost 0.35m SiGe BiCMOS technology are used as a test vehicle to assess the effectiveness of the presented approach. The proposed(More)
