Development of CMOS Transmitter Frontends for UWB Pulse Systems Conference Paper uri icon

abstract

  • New fully integrated single-chip impulse ultra-wideband (UWB) transmitter front-ends, integrating tunable impulse or monocycle-pulse generator with bi-phase shift-keying (BPSK) modulator, have been developed using a standard low-cost 0.18-m CMOS process. The monocycle pulse generator component produces 0.7 - 0.75 V peak-to-peak monocycle pulse with 140 - 350 ps tunable pulse duration. The impulse generator generates 0.95 - 1.05 V peak-to-peak Gaussian-type impulse signal with 100 - 300 ps tunable pulse duration. The BPSK modulator controls the pulse generator to generate positive or negative pulse signal depending on the 1 or 0 digital data information. The pulse signals produced by the developed transmitters are useful for various UWB applications, especially those requiring the capability of changing ranges and resolutions using only a single system. © 2011 IEEE.
