DEVICE FOR ANALYZING BIOMATERIAL BY MEANS OF IMPEDANCE SIGNAL

WIPO Patent Application WO/2018/190458

A1

A device for analyzing a biomaterial by means of an impedance signal according to the present invention comprises: a signal input and output unit for receiving input of analog or digital data from the outside and outputting a digital signal; a direct digital signal combination unit for generating an analog pulse signal by means of processing the digital signal output from the signal input and output unit, wherein the analog signal output from the direct digital signal combination unit is fed-back to the signal input and output unit as a reference signal; a socket unit to which a biosensor accommodating the biomaterial is detachably coupled and to which is transmitted the analog pulse signal output from the direct digital signal combination unit; and a transimpedance amplifier to which is input an analog current pulse signal generated after reaction with the biomaterial of the biosensor coupled to the socket unit and for converting same into an analog voltage pulse signal. An analog voltage pulse output from the transimpedance amplifier is transmitted to the signal input and output unit.
