Abstract: An electrical device and a loop control method are provided. A data signal is obtained from a front end. A variable gain amplifier amplifies the data signal based on a gain value. An analog to digital converter samples the amplified data signal output therefrom to generate a digital data signal. A peak bottom detector detects a peak level and a bottom level of the digital data signal. A threshold controller compares the peak and bottom levels with a threshold value, and generates a first control signal accordingly. An auto gain controller updates the gain value based on the peak and bottom levels with a first step size. The first step size is determined by the first control signal.
