An accurate, very-high-output-resistance active-feedback cascode current mirror has been proposed and compared with a previously reported accurate cascode current mirror. Comparisons have shown that. besides higher accuracy and output resistance, the proposed circuit has no residual error. but has a wider output voltage swing, a much higher PSRR, and an easier and more flexible design.
