Abstract—Oversampled analog-to-digital(A/D) converters architectures offer a means of exchanging resolution in time for that in amplitude so as to avoid the difficulty of implementing complex precision analog circuits.These architectures thus represent an attractive approach to implementing precision A/D converters in scaled digital VLSI technologies. This paper examines the practical design criteria for implementing oversampled converters based on second-order sigma-delta modulation. Behavioral models that include representation of various circuit impairments are established for each of functional building blocks comprising a second-order delta-sigma modulator. Extensive simulations based on these models are then used to establish the major design criteria for each of the building blocks. As an example, these criteria are applied to the design of a modulator that has been integrated in a 3-um CMOS technology. This experimental prototype operates from a single 5-V supply, dissipates 12mW, occupies an area of 0.77 mm*2,and achieved a measured dynamic rang of 89 dB.
