Abstract
Disclosed is a bandwidth adjustment circuit and a bandwidth adjustment method of an operational amplifier. The circuit comprises: a bias current generation unit connected with a bias current input terminal of the operational amplifier and used for providing a bias current to the operational amplifier; a current adjustment unit, connected with the bias current generation unit and an output terminal of the operational amplifier, respectively, and used for adjusting the bias current according to an output voltage of the operational amplifier to realize bandwidth adjustment on the operational amplifier. The bandwidth adjustment circuit and the bandwidth adjustment method can dynamically adjust the bandwidth of the operational amplifier according to the output voltage, not only improving stability when the output voltage of the operational amplifier is low, but also ensuring excellent performance of the operational amplifier when the output voltage is high.
