Abstract
A circuit includes a generating circuit that generates a current signal in response to an input signal, a first one of a plurality of integrators that generates a voltage signal from the current signal, a comparator that is responsive to the voltage signal to compare the voltage signal with a predefined voltage, a switching circuit that reconfigures a first capacitor and a second capacitor connected to the first one of the plurality of integrators to discharge the first capacitor and to enable the second capacitor to generate the voltage signal in response to the current signal, and an analog-to-digital converter to generate an output when a predefined time interval has elapsed. The output is obtained by adding a first charge value corresponding to a count of number of times the voltage signal reaches the predefined voltage in the predefined time interval and a second charge value from the analog-to-digital converter.
