Integrating analog-to-digital converter

摘要

An integrating analog-to-digital converter particularly adapted to measure inertial instrument outputs for strap-down navigation. In the converter, an input signal is summed with a number of precisely quantized voltage pulses and is integrated. An error signal at the output of the integrator controls the rebalance duty cycle of the converter. Counting the net rebalance quanta over an interval results in an output count which is proportional to the input signal voltage.
