摘要

In this paper, a CMOS biosensor integrated circuit (IC) focusing on dielectric relaxations of biological water with 120 and 60 GHz oscillator arrays is proposed. To realize label-free biosensing, we focus on frequencies around 100 GHz where changes in the dielectric constant of water become prominent as many a water molecule is bound to biomolecules. To detect the state of the biological water, se...
