Abstract:
An adaptive amplification circuit is disclosed, which includes an operational amplifier including a variable bias current source for providing a variable bias current for the operational amplifier, a simulation unit for simulating operational characteristics of the operational amplifier and transforming a simulation input voltage to a simulation output voltage, and a bias control unit for generating a bias control signal to the variable bias current source according to the simulation output voltage so as to adjust the variable bias current.
