In this paper, we present a single-path multi-bit delta-sigma analog-to-digital converter (Delta Sigma ADC) architecture that uses time as a reference for performing multi-bit digital-to-analog conversion in the feedback path. The architecture uses a voltage-controlled oscillator as a multi-bit quantizer. In the feedback path of the Delta Sigma ADC, the errors due to component mismatch are avoided by using a single-path for all the levels in a multi-bit digital-to-analog converter (DAC), The technique eliminates the need for feedback DAC architectures with static and dynamic component matching.
