  • Signal amplifying system, AC signal generating circuit, amplifying gain acquiring method, and AC signal generating method
    Patent number: 9509268
    Abstract: A signal amplifying system comprising: an amplifying module with a plurality of PGAs coupled in series; a test signal generating circuit, for generating a test signal fed to one test input PGA; and a control circuit. If the test input PGA is not a final PGA, the final PGA outputs an output test signal amplified by the test input PGA and the PGA following the test input PGA, wherein each of the PGA following the test input PGA has a known amplifying gain. The control circuit acquires an accumulated gain for the test input PGA and the PGA following the test input PGA based on the output test signal, and acquires an amplifying gain of the test input PGA based on the accumulated gain.
