Abstract:
A compensated analog-to-digital converter system, comprising:an analog-to-digital converter module, of a type which relies on scaled capacitors to determine an output value; an array of scaled capacitors including first, second and third capacitors, a common line connected commonly to one end of each of the capacitors, a plurality of switched connections, each connected to a second end of each of the capacitors, and switching the second end of said each capacitors between a first potential and a second potential which is different than the first potential, and a voltage source producing a first voltage for said first potential of said first capacitor, and producing a second voltage for said first potential of a second capacitor, said second voltage being different than said first voltage and producing a third voltage for said first potential of a third capacitor, said third voltage being different than said first and second voltages.
