Abstract :
In this paper, we discuss theoretical and practical issues concerning low-voltage and low-power data converters. By looking at a series of constraints affecting the design of basic elements and building blocks, the paper analyzes different architectures for Nyquist rate data converters and discusses important aspects of low-voltage and low-power operation. Following this, the minimization of power consumption in the very popular sigma-delta technique is considered. A number of hints and indications are provided throughout the paper
