Abstract :
The design issues and tradeoffs of a high-speed high-accuracy Nyquist-rate analog-to-digital (A/D) converter are described. The presented design methodology covers the complete flow from specifications to verified layout and is supported by both commercial and internally developed computer-aided design tools. The major decisions to be made during the converter´s design at both the architectural and the circuit level are described and the tradeoffs are elaborated. The approach is demonstrated for a real-life test case, where a Nyquist-rate 8-bit 200-MS/s 4-2 interpolating/averaging A/D converter was developed in a 0.35-μm CMOS technology. The signal-to-noise-plus-distortion ratio at 40 MHz is 42.7 dB and the total power consumption is 655 mW.
