ABSTRACT:
An integrated circuit component is provided for the analog signal-to-frequency conversion independent of temperature variations. The integrated circuit component contains circuits for generating known analog balancing currents in the form of impressed, load-independent currents. The analog input signal is converted into a load-independent current and in sequence with the balancing signals applied to a current controlled oscillator. The frequencies obtained therefrom are converted into digital values by a frequency-to-digital converter. A microprocessor computes the digital value corresponding to the input signal.
