Design of CMOS Scholtz's monocycle pulse generator

In this paper, a new Scholtz's monocycle pulse generator is proposed and simulated on TSMC 0.18 /spl mu/m CMOS technology. Scholtz's monocycle pulse, which has more advantages than the others, is basically achieved from second derivative of Gaussian pulse. Gaussian pulse is roughly achieved on quadrant squarer circuit with hyperbolic tangent input, and then Scholtz's monocycle pulse is generated by second differential operations in passive components. It can be applied to pulse generator in UWB transmitter as well as the wavelet for a correlator in receiver.
