Low Power Nine-Bit Sigma-Delta ADC Design Using TSMC 0.18micron Technology
Sigma-delta ADC is a mixed signal circuit block, which is suitable for on chip VLSI implementation. Applications of mixed signal systems are continuously increasing in an effort to bring the whole system in a chip. The recent technological advances now make the sigma-delta converters practical and their use is becoming widespread and is more advantageous for mixed-signal system realizations. Sigma-delta ADC is a low-cost, low power, high-resolution ADC and has various applications in signal processing, communications systems, consumer and professional audio, industrial weight scales.
