摘要：A technique is described for improving the sampled current accuracy in currentmirror circuits such as are often used to monitor the current output to a load. A

reference voltage is established to feedback the load voltage conditions at the output tothe current reference circuitry, thereby greatly reducing the error in the referencecurrent over that which is produced by prior art circuits. The technique is shown aasapplied to a current limiting circuit for driving an output load. An alternative embodimentis also disclosed.
