Abstract
Magnetic nanotechnologies have shown signi ficant
potential in several areas of nanomedicine such as imaging,
therapeutics, and early disease de tection. Giant magnetoresistive
spin-valve (GMR SV) sensors coupled with magnetic nanotags
(MNTs) possess great promise as u ltra-sensitive biosensors for
diagnostics. We report an integrated sensor interface for an array
of 256 GMR SV biosensors designed in 0.18 µm CMOS. Arranged
like an imager, each of the 16 column level readout channels
contains an a
