Title
A High Data-Rate Energy-Efficient Triple-Channel UWB-Based Cognitive Radio.
Abstract
This paper presents a fully integrated ultra wideband (UWB)-based cognitive radio (CR) transceiver for $1,{text{Gb/s}}$ data-rate energy-efficient short-range wireless connectivity by scavenging triple discrete inactive frequency bands in 3.1–10.6 $,{text{GHz}}$ ISM band. The transceiver including receivers (RXs), transmitters (TXs), spectrum sensors, and synthesizers is implemented in $1,{text{V}}$ $65,{text{nm}}$ standard CMOS technology. A novel pulse generator (PG) enables the TX to meet UWB emission mask and to reduce spectral sidelobe peak by ${ with low power consumption of $3.6,{text{mW}}$ . A dual-mode RX front-end provides quadrature analog correlation (QAC) for analog domain matched filtering during communication and analog wavelet-based energy detection (ED) during spectrum sensing (SS) without changing circuitry. The transceiver achieves the minimum energy consumption of $59.7,{text{pJ/b}}$ with $1.97 times {10}^{-4},{text{bit error rate (BER)}}$ and the maximum energy consumption of $102.3,{text{pJ/b}}$ with $1.25 times {10}^{-3},{text{BER}}$ . Die area is $4.6,{{text{mm}}^{2}}$ with on-die phase-locked loops (PLLs) and pads.
