A programmable analog-to-digital converter

In this paper, a programmable analog-to-digital converter (ADC) is proposed. Based on a flexible switched-capacitor stage, the amplifier and integrator is easily transformed to each other. By manipulating the feed path from the quantizer to the MDAC, the function can be programmed between sigma-delta modulators and pipelined ADCs. At the fixed sampling frequency, the proposed ADC can be programmed for dynamic range, bandwidth and power consumption, which is simple and feasible for a lot of applications, such as programmable component
