| Abstract: |
The paper presents the idea and implementation of a digital nonlinearity measurement of a voltage ramp. The measurement process is based on evaluation of a time period between the moments when an input voltage ramp and an ideal voltage ramp reach the given value. During this period, the clock pulse train is supplied to the counter. By adjusting the pulse frequency and the circuit parameters, it is possible to obtain the nonlinearity readout in a fraction of percent directly. An automatic range determination has been presented when the reference frequency is constant. Calibration and measurement are completed for two slopes (periods) of the voltage ramp. The measurement error for the proposed method and implementation results were evaluated. [ABSTRACT FROM AUTHOR] |
