The article discusses the advantages of the utilization of delta-sigma modulator (DSM). The author states that most commercialized DSMs are made up of switched capacitor technology. He cites that a DSM should have a different (delta) circuit, an integrate (sigma) circuit and a quantization (modulation) circuit comprising of an ADC and a DAC. He adds that the op-ohm feedback induces the quantized output to be subtracted from the input and the result is integrated. He further adds that the comparator on the output functions as the single bit ADC and is the density output.

The article discusses the practicability of integrating delta-sigma modulation with the dual-slope analog-to-digital converter (ADC). It cites the integration of the ADC technique is very useful for industrial applications, wherein many 60-Hz power present in signals can be measured. It notes that the dual-slope integration can function with 20 to 24 bits of resolution. However, it discusses several limitations of a dual-slope ADC integration, including comparator sensitivity, comparator response time and dielectric absorption.
