ABSTRACT:
A method and device for converting voltage to frequency performs an extremely rapid and highly accurate digitization of an analog input signal at a large frequency deviation. An input voltage, which is increased into the positive range, is integrated and compared with a reference voltage which is variable in constant steps. When the integrated voltage is greater than the reference voltage, a binary signal logic "1" is generated. If the integrated voltage is less than the reference voltage, a binary signal logic "0" is formed. When the integrated voltage is less than the reference voltage, a pulse repetition frequency is formed which is proportional to the input voltage. At each pulse, the reference voltage is incremented so that this reference voltage follows the integrated voltage in a step-like manner.
