Abstract
This paper presents the design of an energy detector for ultra-wideband impulse-based applications. It comprises a squarer using a passive mixer and an integrate-and-dump circuit on a single stage. A current-reuse topology was chosen to reduce the overall power consumption. The proposed energy detector targets low data-rate communications for noncoherent receivers, using on-off keying modulations. The circuit has been designed in a CMOS 180-nm process with 1.8-V power supply. The simulation results show a total power dissipation of 287-μW for a 1-Mbps data-rate using an indoor channel model.
