Analogue-to-digital converter with digitally controlled transfer function

Abstract

The author presents a new simple method of shaping the transfer function of a voltage-to-frequency converter. This method is based on changing the time interval in which the reference voltage is connected to the integrator.

Approximation and Correction of Measuring Transducer’s Characteristics

“…That means that using a generator generating an appropriate waveform of reference voltage will enable obtaining a desired A/D converter characteristics, (Janiczek, 1993).…”

Applied Measurement Systems

“…From the point of view of adjusting processing characteristics of A/D double integral converter, the relation ( 16) is important, which indicates the process of reference U REF voltage integration. That means that using a generator generating an appropriate waveform of reference voltage will enable obtaining a desired A/D converter characteristics, (Janiczek, 1993).…”
