No-Latency Interleaved Delta-Sigma ADC for Multiple-Sensor Interfacing Circuits

This paper introduces a multi-channel A/D converter for multi-sensor systems. In conventional Delta-Sigma ADCs, there is a problem of latency in the digital filter when switching inputs during multi -channel A/D conversion. A novel interleaved Delta-Sigma ADC with incorporated analog memories is suc...

Summary:This paper introduces a multi-channel A/D converter for multi-sensor systems. In conventional Delta-Sigma ADCs, there is a problem of latency in the digital filter when switching inputs during multi -channel A/D conversion. A novel interleaved Delta-Sigma ADC with incorporated analog memories is successfully implemented for multiple-sensor interfacing circuits without being affected by latency.
