Abstract
This article presents a new circuit to generate a higher‐order derivative Gaussian pulse for the impulse radio ultra‐wideband (IR‐UWB) communication systems. This IR‐UWB pulse generator is designed and measured with the TSMC 0.18‐μm CMOS process. The circuit is able to generate a symmetrical and low‐ringing pulse in a frequency band from 3.1 to 10.6 GHz. Our work shows that the pulse generator's output pulse width is 500 ps with an amplitude of 40 mV (peak to peak). The measurement results validate our design and the circuit functionality. © 2006 Wiley Periodicals, Inc.
