ABSTRACT:
Expensive electronics heretofore required to minimize errors introduced by component changes, such as voltage offsets, temperature or linearization errors or the like, are avoided by connecting analog sensor and analog-to-digital conversion components all in a novel feedback network with only moderately precise amplifiers, wherein there is automatic compensation through the feedback for such errors in these components, and with only the errors in the amplifiers driving the system producing any impact upon the system operation; and with those errors eliminated by novel chopper stabilization of the whole system, as distinguished from the individual amplifiers.
