A 100 MHz PRF IR-UWB CMOS Transceiver With Pulse Shaping Capabilities and Peak Voltage Detector

Abstract

This paper presents a high-rate IR-UWB transceiver chipset implemented in a 130-nm CMOS technology for WBAN and biomedical applications in the 3.1-4.9 GHz band. The transmitter is based on a pulse synthesizer and an analytical up-converted Gaussian pulse is used to predict its settings. Its measured peak-to-peak output voltage is equal to 0.9 Vpp on a 100 Ω load for a central frequency of 4 GHz, and a supply voltage of 1.2 V, which gives an emitted energy per pulse of 0.64 pJ. The receiver is a non-coherent architecture based on an LNA followed by a peak-voltage detector. A BER of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> is measured for a 3.1-4.9 GHz input peak-to-peak pulse amplitude of 1.1 mV, which corresponds to a sensitivity of -85.8 dBm at 1 Mb/s and gives a communication range estimated to 1.9 m.
