Abstract

A novel analog-to-digital converter (ADC) system using a two-step conversion is disclosed. The ADC system is capable of achieving high sampling rate, low power consumption and low complexity. The new proposed ADC is formed by cascading a flash ADC having high sampling rate and low resolution with a successive approximation (SA) ADC having low power consumption and low sampling rate.
