Differential-to-single-end converter

摘要

A converter that converts a differential input signal to a single-end output signal is provided. The converter includes first, second, third and fourth transistors, and a pair of current sources. The first and second transistors are driven by the differential input signal, and have two conduction nodes coupled to each other and two conduction nodes not coupled to each other. The third and fourth transistors are driven by the differential input signal, and are connected in series with the first and second transistors. The pair of current sources, respectively connected in series with the third and fourth transistors, have a common control node coupled to the second conduction node of the first transistor. The second conduction node of the second transistor generates the single-end output signal.
