Zusammenfassung:Embodiments are directed to a driver circuit including a first amplifier having a voltage follower configured to control a first node to maintain a voltage of the first node at a constant value. By maintaining the first node voltage, the first amplifier having the voltage follower is further configured to have a first amplifier output current into the first node at a value without the effect of the voltage fluctuation. The driver circuit further includes a second amplifier configured to control a second node, wherein the second amplifier is in a current mirror configuration with respect to the first amplifier such that a second amplifier current output is a highly precise mirror of the first amplifier current output.
