Instrumentation amplifier with base current compensator for improved performance

An electronic system, comprising:

• an instrumentation amplifier having a first input, a second input, a first output, and a second output, wherein the instrumentation amplifier comprises:
• a first amplifier path extending from the first input to the first output, wherein the first amplifier path comprises a first modulator, a first bipolar junction transistor (BJT) input stage circuit, a first demodulator, and a first amplifier arranged in series on the first amplifier path;
• a second amplifier path extending from the second input to the second output, wherein the second amplifier path comprises a second modulator, a second BJT input stage circuit, a second demodulator, and a second amplifier arranged in series on the second amplifier path;
• and
• a base current compensator having first base compensator outputs coupled to inputs of the first BJT input stage circuit and second base compensator outputs coupled to inputs of the second BJT input stage circuit, wherein a first BJT voltage input of the first BJT input stage circuit and a second BJT voltage input of the second BJT input stage circuit are coupled to a base compensator voltage output of the base current compensator.
