Journal: Bio-Medical Materials and Engineering, vol. Keywords: Extended-base bipolar junction transistor, urea, SnO2, ITO, CMOS The effect of urea biosensors with different pH values was considered, and the characteristics of urea biosensors based on EBBJT were described. The dynamic range of the urea biosensor was from 1.4 to 64 mg/dl at the 10 mM phosphate buffer solution and the sensitivity of this range was about 65.8 mV/pUrea.
This circuit occupied an area of 1.0 mm × 0.9 mm. Details, datasheet, quote on part number: MMBT589 Category Description, PNP Bipolar Junction Transistor Company, ON Semiconductor Datasheet, Download. This readout circuit, fabricated in a 0.35-um CMOS 2P4M process, operated at 3.3V supply voltage. The gels, fabricated by the poly vinyl alcohol with pendent styrylpyridinium groups, were used to immobilize the urease. Transistors: Bipolar Junction Transistors (BJT) General configuration and definitions The transistor is the main building block element of electronics. The SnO2/ITO glass, fabricated by sputtering SnO2 on the conductive ITO glass, was used as a pH-sensitive membrane, which was connected with a commercial bipolar junction transistor device. The pH variation was used to detect the concentration of urea. E-mail: Ībstract: In this study, a urea biosensor was prepared by the immobilization of urease onto the sensitive membrane of an extended-base bipolar junction transistor. This is a three-layer device where the semiconductor is doped so as to produce a sandwich of either two n-type. Download PSpice for free and get all the Cadence PSpice models.
