Abstract:
1. A hybrid-differential analog-to-digital converter, comprising: a first single-ended analog-to-digital converter having a first input from a voltage signal; a second single-ended analog-to-digital converter having a second input from a signal ground wherein said signal ground is a first reference voltage for said voltage signal; and a programmable device in communication with a first output of said first single-ended analog-to-digital converter and a second output of said second single-ended analog-to-digital converter, said programmable device provides a digital result that is said second output subtracted from said first output, wherein said digital result is free from common-mode noise, wherein said voltage signal corresponds to an output from a sensor coupled with said hybrid-differential analog-to-digital converter and said first reference voltage is a sensor ground of said sensor.
