High output dynamic UWB pulse generator for BPSK modulations

Abstract

This paper presents the design of a fully integrated pulse generator which allows BPSK modulation to be implemented. This emitter is based on the response filter architecture and has been integrated in a 130 nm CMOS technology with a 1.2 V supply voltage on a silicon area of 2.88 mm2. The bandwidth at -10 dB is about 1.8 GHz around 3.52 GHz. The output dynamic voltage is equal to 1.72 V peak to peak on a 100 Ω differential load which gives an energy of 1.93 pJ for the twice bipolar generated pulses and demonstrates the pulse generator capability to be used for bipolar modulations.
