Correlated Multiple Sampling Techniques for Sensor Signal Conditioning
Correlated Double Sampling (CDS) is a widely used technique in sensor signal conditioning. It effectively cancels offset and low-frequency (flicker) noise. CDS is a discrete time signal processing technique, implemented with Switched Capacitor (SC) circuits or after ADC with a Digital Signal Processing (DSP) algorithm. This paper describes a simple approach wherein the CDS technique is extended to Correlated Multiple Sampling (CMS) techniques, and with the price of processing of more samples, the new CMS techniques greatly improves the amplifier offset and flicker noise suppression.
