Abstract

An apparatus for performing level shift control in an electronic device includes an input stage positioned in a level shifter of the electronic device, and an output stage positioned in the level shifter and coupled to the input stage through a set of intermediate nodes. The input stage is arranged for receiving at least one input signal of the level shifter through at least one input terminal of the input stage and controlling voltage levels of the set of intermediate nodes according to the at least one input signal. The input stage includes a hybrid current control circuit coupled to the at least one input terminal and arranged for performing current control for the input stage. The hybrid current control circuit is equipped with multiple sets of parallel paths for controlling currents passing through the set of intermediate nodes, respectively, each set may include two or more paths in parallel.
