WU Jian-wei, ZHAO Ying-kai. Design of signal regulating circuit used in electrolyte analyzer[J]. 2009, 28(1): 101-102+105. DOI: 10.13873/j.1000-97872009.01.036.
In order to measure the pattern effectively in the test system of electrolyte analyzer
the ISE is used as the converter.The signal regulating circuit is designed through analysis of the characteristic of outcoming signal of ISE.The application of high input impedance operational amplifiers CA3140 as the key part in the signal amplifying circuit is testified by experiment.Experimental data is listed to testify the ideal result of the circuits.
