Abstract :
This paper describes the design of a two-step analog-to-digital converter (ADC). By using techniques such as improved switching and offset compensated amplifiers, the high-speed two-step architecture can be expanded toward high resolution. The ADC presented here achieves 9 ENOB with a spurious-free dynamic range of more than 72 dB, at a sample rate of 25 MSample/s. The ADC is realized in a 0.35-μm mainstream CMOS process without options such as double poly. It measures 0.66 mm 2 and dissipates 195 mW from a 3.3-V power supply
