CUT-OFF FREQUENCY REGULATOR |
摘要 |
FIELD: filters built around integrated circuits. SUBSTANCE: device that functions to regulate cut-off frequency using electrode-to-electrode active conductivity has filter unit 100 incorporating electrode-to-electrode active conductivity unit 10 provided with variable resistor with electrode-to-electrode active conductivity on first and second transistor 10a, 10b regulated by control voltage supplied from electrode-to-electrode active conductivity control unit. Frequency response of filter circuit installed in integrated circuit is maintained constant irrespective of temperature and supply voltage fluctuations, and manufacturing defects. EFFECT: improved reliability of cut-off frequency regulation. 10 cl, 7 dwg |
