Abstract:
An adaptive amplification circuit is provided, which includes an operational amplifier comprising a variable bias current source for providing a variable bias current for the operational amplifier, an equivalent circuit of the operational amplifier for receiving an input voltage and generating an output voltage according to the input voltage, and a bias control unit for generating a bias control signal to the variable bias current source according to the output voltage so as to adjust the variable bias current.
