Abstract: A monolithic integrated high resolution analog-to-digital converter based on a charge balancing process, characterized in that the output of a charge balancing integrator is connected to the control input of a pulse width modulator. An output of the pulse width modulator controls the temporal activity of the feedback signal in the charge balancing integrator. The output of the pulsewidth modulator is also connected to a digital calculation circuit which evaluates the pulse width result of the conversion. The input of the analog-to-digital converter is connected to one input of the charge balancing integrator and the feedback signal from the pulse width modulator is connected to the other input.
