Abstract
A compact and robust magnetic label detector for
biomedical assays is implemented in 0.18- mC M O S .D e t e c t i o n
relies on the magnetic relaxation signature of a microbead label
for improved tolerance to enviro nmental variations and relaxed
dynamic range requirement, elim inating the need for baseline
calibration and reference sensors. The device includes embedded
electromagnets to eliminate external magnets and reduce power
dissipation. Correlated double sampling combined with offset
