Abstract

An apparatus for stabilizing cut-off frequency using a transconductance, especially used in a high-frequency filter circuit, capable of maintaining constant frequency characteristics regardless of noise in association with a clock frequency, changes in the temperature, changes in the power supply voltage and errors in fabrication, when a filter circuit is installed in an IC (Integrated Circuit). The apparatus includes a filtering unit for passing only signals having a frequency band predetermined in the IC; a transconductance setting unit, installed out of the IC, for controlling a transconductance of the filtering unit; and a controlling unit for controlling a transconductance of the transconductance setting unit.
