Abstract

In this paper, we discuss how asynchronous design techniques can be used in the implementation of continuous-time signal processors. Such processors are presented by signals developed by continuous-time analog-to-digital converters which involve no sampling, and thus do not exhibit aliasing; in addition, the resulting in-band quantization error is lower than in conventional techniques. Several design considerations are given, and preliminary experimental results are presented.
