Abstract
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.
