A 1-Gb/s 6–10-GHz, Filterless, Pulsed UWB Transmitter With Symmetrical Waveform Analysis and Generation

This paper presents a fully integrated, regulation-aware pulsed ultra wideband (UWB) transmitter (TX) for low-cost, high-data-rate applications. Waveform nonidealities have been systematically analyzed for the first time, demonstrating that envelope asymmetry may cause spectrum regulation violations. In order to generate regulation-compliant UWB pulses without costly filters, the proposed high-data-rate TX employs an intrinsically symmetrical carrier-based pulse generation scheme. The prototype was fabricated using a 130-nm CMOS process, occupying 0.37 mm2. This biphase-modulated TX can support a measured maximum data rate of 1 Gb/s with a pulsewidth of 0.5 ns and a power efficiency of 14.4 pJ/b. Without filters, the output spectrums are not only compliant with the regulations but also consistent with the theoretical results.
