Title: Logarithmic transformation device
Inventor: SAITO HIROSHI
IPC: H03G11/08
Filed: 1987-09-10
Abstract: PURPOSE:To stably obtain a temperature compensation circuit with high accuracy by utilizing it that a potential difference after logarithmic transformation between an input current and a constant current is proportional to the absolute temperature, extracting a current proportional to another absolute temperature from a capacitor whose potential is raised by the current proportional to the former absolute temperature thereby restoring the potential to the original potential. CONSTITUTION:An input current is subjected to logarithmic transformation while applying current/voltage (I-V) conversion by a diode 5, a difference between an output voltage and a voltage across the diode 5 causing another constant current to flow is obtained and the difference is subject to voltage/current (V-I) conversion and a current flows to a capacitor 9 having a preset reference potential. Then a current proportional to the absolute temperature is extracted from the capacitor 9 and the potential of the capacitor 9 is restored to the reference potential thereby making the time when the potential of the capacitor 9 rises from the reference potential independent of the time when the potential falls down and restores to the reference potential in terms of temperature. Thus, the output of a logarithmic transducer independently of the temperature is obtained stably with high accuracy.
