A simple circuit for generating wavelets required in an ultra-wideband (UWB) impulse radio receiver is presented. The second derivative G 2 (t) of the Gaussian function is approximated by combining multiple hyperbolic tangent (tanh) functions. Simulations show that a good approximation of this waveform is possible using integer coefficients. A bipolar transistor circuit implementation is presented and its simulation results shown.
