Introduction In precision analog measurement systems, the accuracy of every microvolt-level signal path contributes directly to overall system performance. Whether measuring current in medical instrumentation, industrial controls, laboratory equipment, or high-fidelity audio amplifiers, the performance of the current sense resistor frequently establishes the ultimate accuracy, stability, and repeatability of the entire measurement chain. Unfortunately, today's electronics sup

As electronic systems continue to evolve toward higher sensitivity and greater autonomy, measurement accuracy has become a defining performance parameter rather than a desirable feature. In sectors such as medical electronics and humanoid robotics, signal levels often exist in the microvolt range, where even seemingly insignificant electrical phenomena can compromise system integrity. One frequently overlooked contributor to measurement error is stray voltage generated by the
