摘要

In this paper, the analysis of a current feedback compensation architecture compatible with pixels having the 2-transistors and 1-capacitor structure is evaluated. The aim of the circuit presented and analyzed, is to cleanly reach a programming pixel current level below 50 nA with an average 10% of error. Here, we also present the method to achieve robustness in the operation of the loop, observed...
