Abstract

This paper presents a fully integrated GMR biosensor chip for point-of-care in vitro diagnostics featuring on-chip sensors, excitation coils, and a digital back-end. The system achieves$120 \text{nT}_{\text {rms }}$noise, 0.38 ppm sensitivity,$21 \times$faster readout and$10 \times$lower baseline with full integration. Real-time IL-6 immunoassay results demonstrate high specificity and multiplexing, enabling compact, high-throughput PoC testing.
