Driving circuit capable of enhancing response speed and related method
Abstract:
A driving circuit of enhancing response speed is disclosed. The driving circuit includes an operational amplifier and a slew rate enhancement unit. The operational amplifier is utilized for generating a driving voltage according to an input voltage. The slew rate enhancement unit is coupled to the operational amplifier, and is utilized for generating a compensation current to the operational amplifier to enlarge a bias current of the operational amplifier according to voltage difference between the input voltage and the driving voltage when variation of the input voltage occurs.
