Abstract:
1. A current driver circuit comprising: an input node adapted to receive an input current; an output node adapted to drive an output current; a solid voltage module having a first input coupled to a reference voltage and a second input coupled to the input node, the solid voltage module including an operational amplifier having a non-inverting node coupled to the reference voltage and an inverting node coupled to the input node, the operational amplifier configured to have a voltage of the inverting node the same as the reference voltage; a current receiving module coupled to an output of the solid voltage module and the input node, the current receiving module configured to drive the input current from the input node; and a current mirror module coupled to the current receiving module and the output node and configured to receive the input current from the current receiving module and drive an output current from the output node that is multiple times the input current.
