Abstract :
A switched differential current mirror with an offset cancellation technique is presented. Because of its symmetrical signal paths, the charge injection in nominal is minimized. By the means of statistical simulation, the error caused by local parametric variations between the switching elements has been estimated. Methods making the current mirror more robust against local mismatching of the switches are proposed. Statistical simulations are presented and discussed
