An UWB transmitter with power cycling and support for multiple modulation schemes

Abstract

A reconfigurable ultra-wideband transmitter using 0.13 µm CMOS technology is presented. The transmitter supports three different modulation schemes: binary phase shift keying, transmitted reference binary phase shift keying and onoff keying. The circuit contains glitch generators that modulate an oscillator combined with a power cycling controller which reduces the power consumption. The simulated output center frequency can be adjusted from 4 to 9 GHz and the transmitter achieves data rates ranging from 1 to 100 Mbps with a power consumption as low as 200 μW at 1 Mbps.
