Automatic gain controllers and methods for controlling voltage of control gain amplifiers |
摘要 |
An automatic gain controller includes a voltage control gain amplifier amplifying input signals in response to a control voltage and producing output signals. A level detector detects peak and bottom levels of the output signals of the voltage control gain amplifier, and an analog-digital converter (ADC) converts the detected peak and bottom levels into digital signals. A peak detector detects a digital peak in response to a difference between the digital peak level and digital bottom level, and a voltage controller compares the digital peak and a reference voltage, and controls the control voltage.
