A Flexible, Low Power, DC-1GHz Impulse-UWB Transceiver Front-end

A flexible, low power, "mostly-digital", DC-1 GHz impulse-UWB transceiver front-end is presented. By duty-cycling nearly all of the circuitry with the pulse rate, power consumption of 570 muW (RX) and 350 muW (TX) is presented at 1 Mpulse/s with 1-bit, 1.92 GSample/s sampling, 50 Omega input matching, and 42 dB of gain at 1.1 V. Additionally, the transceiver allows for variable modulation (PAM, PPM or both), variable gain (0 to 42dB), independent timing control for each block, variable input impedance and pulse shape generation, limited pulling of the oscillator frequency, and gain stage offset trimming to 1 mV
