4.7pJ/pulse 7th Derivative Gaussian Pulse Generator for Impulse Radio UWB

Abstract—This paper presents a ultra low-power, lowcomplexity circuit to generate the monocycle pulse for Impulse Radio UWB (IR-UWB) applications. A 7th order derivative Gaussian pulse is generated using the edge combination technique plus an extra derivative circuitry. The proposed pulse generator is designed using TSMC 0.18 µm CMOS process. Simulation shows 500 mV of pulse amplitude and 800 ps of the pulse duration. Generated pulse spectrum fully complies with the FCC spectrum mask for out-door applications, especially in the range of 3.1–5.1 GHz. The pulse generator dissipates no static current with only dynamic
