Abstract
An accurate, low noise conditionally resetting integrator circuit in an analog to digital system samples, with an analog to digital converter, the output of an integrating circuit a number of times during a measuring period; isolates the input for the integrating circuit during sample event; generates a reset signal in response to the integrating circuit output reaching a predetermined level; and resets the feedback capacitor of the integrating circuit by isolating it from the amplifier circuit of the integrating circuit and connecting it to a reference source during a sample event.
