Control voltage for baseband channel selection filter to select one of communication channels can be easily fluctuated according to external noise or variation of fabrication. In this paper, we design a voltage regulator with small chip area to keep control voltage constantly using current comparative method. Cut-off frequency of channel selection filter is automatically controlled by detecting current flow using the proposed voltage regulator.
