Abstract : a noise model for the analog correlator used in the ultra wideband receivers is proposed due to lack of simulation capability on noise performance of the correlator in current eda tools. the analog correlator circuit is divided into several parts to calculate the equivalent noise sources respectively. the ideal impulse generators, instead of the noise sources, are then applied to obtain the time varying transfer functions. fourier transforms are carried out to explore the relationship between the noise input and output in frequency domain for each part. then the symmetrical noise sources are grouped together and the periodicity of the circuit is utilized to further simplify the model. this model can be used to evaluate noise performance of the correlator
