1. A method for producing a signal representative of temperature, comprising:

  • producing a first current proportional to temperature;

    producing a second current inversely proportional to said temperature;

    selectively using said first and second currents to control the charge on a capacitor; and

    comparing the charge on said capacitor to a reference voltage to produce a bitstream representative of said temperature.
