Paper Abstract

In this paper we propose a compact current mode calibration technique for analog current mode circuits operating in weak inversion. The technique is based on the use of MOS ladder structures controlled by a locally stored digital calibration word. Extensive Monte Carlo have been performed to analyze the technique. The circuit has been applied to calibrate a circuit intended for use in a contrast retina.
