Abstract
A time/analog converter for adjusting the zero point and amplification of the output characteristic of a sensor includes an integrator whose output is connected to the input of a holding member. A reference voltage and the output voltage of the holding member occur at the input of the integrator. A control means actuates switches connecting the integrator to the holding member and applying the reference voltage and the output voltage to the input of the integrator so that the reference voltage is at the integrator input for a first time interval and the holding member output voltage is at the integrator input for a second time interval. The integrator output voltage is applied to the holding member for a third time interval. A controllable pulse shaper is connected to one of the switches and can close it for a required time interval. A related method is also described.
