An ultra-wideband transmitter based on a new pulse generator

Abstract

The paper describes an ultra-wideband transmitter, which incorporates an innovative carrier-based pseudo-Gaussian pulse generator satisfying FCC rules with no-filter and high spectral efficiency. The design includes a BPSK modulator, a ramp generator and an output buffer. The transmitter is designed for run up to 500 Mpps in the UWB 3-5-GHz band and it is implemented in 0.28-mum CMOS technology with a core chip size of 0.06-mm2. It allows the use in various UWB applications. Pulse generator dissipation is 1.9-mW.
