ABSTRACT:
Embodiments of the present invention are directed to current driver circuits and methods for driving a load. The current driver circuit includes a first transistor (Q1) and a second transistor (Q2) each having a gate, a drain and a source. The drain of the second transistor (Q2) forms the output of the current driver circuit. The first and second transistors (Q1) and (Q2) function as a current mirror when the gates of the first and second transistors (Q1) and (Q2) are selectively connected together. The current driver circuit also includes a current source, a load mimic circuit, and a control loop (e.g., including an op-amp), which are configured to cause the voltage at the drain of the first transistor (Q1) to substantially equal the voltage at the output of the current driver circuit.
