Abstract

This paper proposes a 0-33.3Mb/s front-end of the energy detector for 3.1-4.8-GHz impulse-radio ultra-wideband (IR-UWB). Fully differential architecture with the non-coherent on-off-keying (OOK) modulation is adopted. Targeting at - 98dBm sensitivity, the low noise amplifier (LNA) is designed to achieve <3.5dB noise figure, <-10dB S11, and >15dB gain. Interleaved integrating scheme relaxes the implementation of digital circuits. Thanks to the duty-cycling, the front-end achieves 420pJ/bit energy efficiency for OOK modulation. The bias is generated by band-gap circuits. The layout design and verification are completed with Cadence Spectre using UMC 90nm CMOS.
