Abstract

On-chip sine-wave signal generation is widely covered by literature for Built-In-Self Test (BIST) or biosensor applications. The objective is to generate pure and robust sinewave signal with minimal hardware resources. An attractive solution consists in combining several digital signals to built this analog sine-wave. The objective of this paper is to give an analytical study of various potential solutions based on digitalbased approaches. Thanks to this study, we prove that technique consisting in setting the phase shifts and various amplitude values of the square-wave signals is the most efficient approach. Moreover, this study allows the selection of the best solution in terms of parameters of the square-wave signals to cancel loworder harmonics of the generated signal.

基于组合数字信号的片上模拟正弦波生成分析研究
片上正弦波信号的产生被文献广泛覆盖,用于内置自我测试(BIST)或生物传感器应用。目标是用最少的硬件资源生成纯粹和鲁棒的正弦波信号。一个有吸引力的解决方案是将几个数字信号组合在一起来构建这个模拟正弦波。本文的目的是对基于数字化方法的各种潜在解决方案进行分析研究。通过本研究,我们证明了设置方波信号的相移和不同幅度值的技术是最有效的方法。此外,本研究允许根据方波信号的参数选择最佳解决方案,以抵消生成信号的低阶谐波。
