Abstract:

This paper presents the development of a lab-on-a-chip for cellular analysis with

the implementation of RF biosensors based on injection-locked oscillators. The proposed

circuit can evaluate the dielectric response of suspended cells circulating in a microfluidic

channel. Under these conditions, a detection accuracy of a few attoF is necessary to

discriminate differences between cells. For oscillators operating in free running frequency,

it would generate variations of the oscillation frequency of the order of 10 kHz near 5 GHz,

which is very complex or almost impossible to detect. We propose here a relevant

approach.

Keywords:

RF biosensor, BiCMOS, Biological cells, Injection locked oscillators.
