Integrator that prevents signal saturation for analog-to-digital converters (ADCs)

Summary

The analog integrator is a fundamental component in analog-to-digital converters (ADCs), control systems, and analog computers. However, input signals with high amplitudes may cause conventional analog integrators to produce an output that becomes saturated at the supply voltage. In this case, the output signal does not accurately reflect the input. This technology employs a mixed signal analog-digital circuit to prevent output saturation, resulting in a more accurate signal.
