An inductorless CMOS UWB pulse generator with active pulse shaping circuit

The design of an UWB pulse generator is presented. The pulse generator is based on an elementary pulse combination technique which enables the emitted pulse to be precisely shaped. This technique is implemented with no inductor or passive network and can be used to ensure regulation compliance. This generator has been fully integrated in a 0.13 μm CMOS standard technology. Its area is 0.06mm² only and it can be programmed to synthesize different pulse shapes. For FCC compliant pulse shapes, the maximum measured 10dB bandwidth is 3.5GHz, and the maximum peak to peak magnitude is 220mV. The measured maximal power consumption is 87.6mW at 800MHz Pulse Repetition Frequency (PRF).
