In described examples of systems and methods for load current compensation for analog input buffers, an input buffer (300) may include: a first transistor (Q1) having a collector terminal coupled to a power supply node and a base terminal coupled to a first input node (vinp); a second transistor (Q2) having a collector terminal coupled to an emitter terminal of the first transistor (Q1); a third transistor (Q3) having an emitter terminal coupled to an emitter terminal of the second transistor (Q2) and to a ground node, a collector terminal coupled to a current source (Ibias), and a base terminal coupled to the collector terminal and to a base terminal of the second transistor (Q2); and a capacitor (C1) coupled to the base terminals of the second and third transistors (Q2 and Q3) and to a second input node (vinn), wherein the first and second input nodes (vinp and Vinn) are differential inputs. |
