A device is provided for time measurement of a clock-based signal comprising a sample stage comprising a switching device that is driven by a control signal and a capacitance (Cs), wherein the sample stage is arranged to transform an analog input signal in an analog output signal, the device further comprising an analog-to-digital converter to convert the analog output signal into a digital output signal, wherein the input signal applied to the sample stage is a reference signal and wherein the clock-based signal is applied to the control signal. Also, an according method is suggested.
