Abstract or Summary
  • The advance of digital IC technology has been very fast, as shown by rapid development of DSP, digital communication and digital VLSI. Within electronic signal processing, analog-to-digital conversion is a key function, which converts the analog signal into digital form for further processing. Recently, low-voltage and low-power have become also an important factors in IC development. This thesis investigates some novel techniques for the design of low-power high-performance A/D converters in CMOS technology, and the non-ideal switched-capacitor effects of (SC) circuits. A new successive-approximation A/D converter is proposed with a novel error cancellation scheme. This A/D converter needs only a simple opamp, a comparator, and a few switches and capacitors. It can achieve high resolution with relative low power consumption. A new ratio-independent cyclic A/D converter is also proposed with techniques to compensate for the non-ideal effects. The implementation include a new differential sampling that is used to achieve ratio-independent multiple-by-two operation. Extensive simulations were performed to demonstrate the excellent performance of these data converters.
