A logarithmic (LOG) based adaptive algorithm to track RF power received at a receiver is provided. The method includes: receiving, by a variable gain amplifier (VGA) having exponential gain characteristics, an input signal; and providing log-based gain control of the input signal by determining a power of the input signal, and generating, according to the determined power, a voltage control signal using a log-based function, wherein the VGA amplifies the input signal based on the voltage control signal. |
