  • Automatic gain control circuit for analog signals
    Patent number: 6577191
    Abstract: A front-end signal-processing device having an automatic gain-control function used in the analog-to-digital conversion. The circuit comprises a buffer circuit, an amplifying/attenuating circuit, a pre-processing gain-adjusting circuit and an amplification/attenuation gain-adjusting circuit. In the front-end signal-processing device having an automatic gain-control function used in the analog-to-digital conversion, a set of gain-adjusting signals S1 and S2 are produced by hardware for controlling the amplification or attenuation gain of signals, thereby automatically adjusting the amplitude of the input signals. In addition, the microprocessor can select an appropriate restoring parameter according to the gain-adjusting signals to ensure that the numeral result conforms to the original input signal.
