摘要：The solution according to the invention consisting in conversion of a timeinterval to a digital word of a number of bits equal to n by the use of the array (A) of

binary-scaled capacitors (C., . . . , C) is characterized in that the time interval whose bothstart and end are detected by the control module (CM) is first mapped to a portion ofelectric charge delivered by the current source (I) and successively accumulated in thecapacitors ((C, . . . , C)) in the order of decreasing capacitances starting from the capacitor(C) having the highest capacitance value in the array, and when the control module (CM)detects the end of the time interval, the charge accumulated in the capacitor (C) chargedrecently is successively transferred by the use of the current source (I) to the capacitorsof lower capacitance values. The process of charge transfer is controlled by the controlmodule (CM) on the basis of the output signals of the comparators (K) and (K) withoutthe use of a clock while the value one is assigned to these bits (b, . . . , b) in the digitaloutput word that correspond to the capacitors (C, . . . , C) on which the reference voltage(U) of a desired value has been obtained, and the value zero is assigned to the other bits.
