    • Apparatus (1) and corresponding method for measuring a current (10) in which a charge integrating circuit (2) integrates charge from the current to be measured (10) and applies a resulting change in voltage to a comparator circuit (4) that compares the input voltage (12) with a threshold voltage level (Vthreshoid) and provides an output (14) responsive thereto to a logic circuit (6) that generates a feedback signal (16) dependent upon the comparator output (14) and provides the feedback signal (16) to the charge integrating circuit (2) that integrates charge from the received feedback signal (16) in opposition to the integrating of the charge from the current to be measured (10). The logic circuit (6) generates an output signal (18), based upon the comparator circuit output (14) and dependent upon the level of the current to be measured (10), for example a pulse (50) of a width (TOUT) dependent upon the level of the current (10). A converter circuit (8) may convert the output signal (18) to digital output data (20).
