Abstract :
This paper presents and compares the structure and performance of new alternate architectures developed for spectral noise shaping in over-sampled analog-to-digital and digital-to-analog converters. These architectures differ from conventional design approaches in two ways. The primary difference is in the distribution of transmission zeros in the noise transfer function, while the secondary difference is the manner in which the architecture forms these transmission zeros
