Abstract:
An analog amplifier for amplifying an analog signal and an analog filter is provided. In particular, an apparatus and method for controlling gain and cutoff frequency of the variable gain amplifier and the variable cutoff frequency filter that is capable of changing the gain and cutoff frequency are provided. The variable resistor includes a plurality of resistor segments in the variable resistor and, when a plurality of resistance candidates for the variable resistor is arranged in order of size, the resistance candidates form a geometric series.
