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

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 $0.9~V_{\mathrm{ pp}}$ on a 100 $\Omega $ 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 10−3 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.
