Abstract :
This paper presents a fully integrated all-digital ultra-wideband (UWB) transmitter. All functional blocks in the transmitter are implemented with digital standard cells and automatically placed-and-routed (APR-ed) by design tools. The center frequency and the bandwidth of the UWB pulses are digitally tuned to compensate for variations, and a calibration scheme utilizing APR mismatch is explored. The transmitter is fabricated in a 65nm CMOS process, and occupies a core area of 0.036mm2. The transmitter operates in the 3.1-6GHz UWB band, and the active energy consumption ranges from 12pJ/pulse to 38pJ/pulse.
