Abstract

The invention provides a current mirror circuit with high driving ability and output buffer device using the same, in which gate electrodes of input transistors of the current mirror circuit are respectively connected with an operational amplifier, so that the operational amplifier acts as a voltage follower which is further connected with the gate electrode of each output transistor for generating stable and accurate bias signals, thereby significantly increasing the driving ability of the current mirror circuit. In addition, the current mirror circuit can be used in conjunction with a buffer driving circuit and an input receiver circuit for generating corresponding output driving signals according to received differential input signals, thereby greatly reducing circuit layout area of the output buffer device.
