This work presents a high rate IR-UWB transceiver chipset implemented in a 130 nm CMOS technology for WBAN and biomedical applications in the 3.1GHz-4.9GHz band. The transmitter is based on a pulse synthesizer and an analytical upconverted Gaussian pulse is used to predict its settings. Its measured peak to peak output voltage is equal to 0.9Vpp on a 100 load for a central frequency of 4GHz, and a supply voltage of 1.2V, which gives an emitted energy per pulse of 0.64pJ. The receiver is a non-coherent architecture based on a LNA followed by a peak voltage detector. A BER of 10-3 is measured for a 3.1GHz-4.9GHz input peak-to-peak pulse amplitude of 1.1mV which corresponds to a sensitivity of-85.8dBm at 1Mbps and gives a communication range estimated to 1.9m.
