Abstract :
Ultra-wideband (UWB) pulse generator circuit is said to be the heart of any UWB systems. It is the fundamental circuit for application and development of UWB technology. This paper presents an UWB pulse generator with cascode transistors operating as a pulse shaping circuit to generate Gaussian pulses. In this work, the UWB pulse generator consists of three parts: an edge triggered driver, an edge sharpener SRD, and a cascode for impulse shaping. The proposed circuit allows the generator to create short and high amplitude Gaussian-like pulses at low-cost. Our measured UWB pulse was 1.0 ns pulse with 2.8 Vpeak.
