Abstract
The ladder network of a recirculation of remainder analog to digital converter has a voltage source that is regulated by a transistor and Zener diode together with feedback circuitry responsive to the regulated output voltage. Current through the circuit is controlled by feedback to establish equal and opposite temperature coefficients in the transistor and Zener diode of the regulator. The temperature stabilized voltage regulator produced thereby eliminates any requirement for trimmer potentiometers.
