Abstract
It is difficult to measure and process the signals for battery due to weak effective signal accompanied by strong noise. This paper designs a phase lock amplifying circuit based on balanced and modulated/demodulated chip AD630. The working principle is described in detail. The relationship between input and output is derived. The experimental result clearly indicates that the method is simple, practical and has high precision.
