A Very Low-Complexity 0.3-4.4 GHz 0.004 mm2 All-Digital Ultra-Wide-Band Pulsed Transmitter for Energy Detection Receivers.

This paper presents a very low-complexity all-digital IR-UWB transmitter that can generate pulses in the band 0-5 GHz, requiring a silicon area lower than a PAD for signal I/O. The transmitter, suited to non-standardized low data rate applications, is prototyped in a 130 nm RFCMOS technology and includes analog control signals for frequency and bandwidth tuning. Center frequency is linearly select...
