Abstract
Systems and methods for load current compensation for analog input buffers. In various embodiments, an input buffer may include a first transistor (Q) having a collector terminal coupled to a power supply node and a base terminal coupled to a first input node (v); a second transistor (Q) having a collector terminal coupled to an emitter terminal of the first transistor (Q); a third transistor (Q) having an emitter terminal coupled to an emitter terminal of the second transistor (Q) and to a ground node, a collector terminal coupled to a current source (I), and a base terminal coupled the collector terminal and to a base terminal of the second transistor (Q); and a capacitor (C) coupled to the base terminals of the second and third transistors (Qand Q) and to a second input node (v), wherein the first and second input nodes (vand v) are differential inputs.
