Abstract
A device for measuring low currents is proposed to include: a transimpedance amplifier to convert an analog current signal into an analog voltage signal; an analog-to-digital converter to acquire a graph that plots a curve representing variation of the analog voltage signal using digital codes; a statistic module to acquire a set of crossing numbers by: for each of the digital codes, making a straight line that has a constant value equaling the digital code across time in the graph, and counting a number of crossings of the curve with the straight line; and an analysis module to analyze distribution of the crossing numbers, and to output an output code based on the distribution of the crossing numbers.
