Abstract :
The possibility of using CAD tools to produce high-performance ΣΔ modulator (ΣΔM) ICs is illustrated in this paper through the design of a low-power 2nd-order ΣΔM. It is intended to be used in the front-end of a CMOS 0.7 μm energy metering ASIC. The fabricated prototype features 16.4-b dynamic range (DR) for 9.6-ksample/s output rate with a power budget of 1.71 mW. Such performance places this ΣΔM IC between those reported up to now with lowest value of the Power(W)/2resolution(bit)×Output Rate(Hz) figure
