Circuit for converting input current signal to digital output signal has input node, reference node, converter, comparator, clocked counter that generates digital signal, digital-analog converter

摘要

The circuit has an input node (12a), a reference node (12b) for tapping a comparator input signal, a converter for converting the analog input current signal into the comparator input signal, a comparator, a clocked counter that generates the digital signal and a digital-to-analog converter for converting the digital output signal into an analog feedback current signal. An Independent claim is also included for a method of converting input current signal to corresponding digital output signal.
