1. An A/D converter comprising:

  • a first voltage to current converter which generates an input current from an analog input voltage;

    a current reference for generating first reference current;

    a first plurality of scaling elements for generating a plurality of scaled reference currents;

    a second plurality of scaling elements for generating a plurality of scaled input currents; and

    a plurality of current comparators which compare the scaled input currents to the scaled reference currents to generate a thermometer code.
