Abstract
An all-digital UWB TX is presented that generates PPM pulses with a center frequency tunable to 3 channels in the 3.1-to-5GHz band without the use of an RF oscillator. A delay-based spectral scrambling technique is proposed that exploits the digital architecture. The circuit achieves 47pJ/b at a data rate of 10Mb/s.
