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 130nm CMOS technology with a 1.2V supply voltage on a silicon area of 2.88mm². The bandwidth at -10dB is about 1.8GHz around 3.52GHz. The output dynamic voltage is equal to 1.72V peak to peak on a 100Ω differential load which gives an energy of 1.93pJ for the twice bipolar generated pulses and demonstrates the pulse generator capability to be used for bipolar modulations.
