Voltage Measurement with Improved Multi-Slope Integral Analog-to-Digital Converter

Abstract:

This paper presents a 20 Hz to 200K Hz alternating current (AC) and direct current (DC) analog-to-digital converter (ADC). The strange to minimize the zero crossing noise adopts hysteresis comparison technique. Multi-slope integral technique is also employed to enhance measurement accuracy. Furthermore, an algorism is designed to eliminate measure error. The prototype ADC achieves millivolt precision.
