This paper discusses the use of continuous-time sigma-delta modulators for ADCs in wireless

biomedical sensing applications. The advantages of the proposed continuous-time sigma-delta

modulators include the fact that it eliminates the need for an anti-aliasing filter in front of the ADC

because of its intrinsic anti-alias filtering property. Additionally, the use of weak inversion and a low

flicker noise structure minimizes power consumption and low frequency flicker noise. Finally, the

decimation filter used in ordinary sigma-delta ADCs to attenuate high-frequency noise is eliminated

because the biomedical sensor analyzes the periodogram in software, thus significantly reducing the

cost and power consumption. A design example illustrating these advantages is presented in this paper.
