An ideal radio communication receiver places the analog to digital conversion just after the antenna. It is an objective in a Òsoftware radioÓ perspective. The available silicon technologies do not provide the performance required by this application. We are able to evaluate the present limits and the gap between these limits and the ideal solution proposed. In this paper, we describe the prese...

There exist measuring devices where an analog input is converted into a digital output. Such converters can have a nonlinear internal dynamics. We show how measurements with such converting devices can be understood using concepts from symbolic dynamics. Our approach is based on a nonlinear one-to-one mapping between the analog input and the digital output of the device. We analyze the Bernoull...

Delta-sigma modulation for analog-to-digital conversion resolves a number of bits logarithmic in the number of modulation cycles, and linear in modulation order. As an alternative to higher-order noise shaping, we present an algorithmic scheme that iteratively resamples the modulation residue, by feeding the integrator output back to the input. This yields a bit resolution linear in the number ...
