ANALOG SENSOR SIGNAL PROCESSING METHOD, MEASURED VALUE PROCESSOR, AND GAS SENSOR ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide an improved analog sensor signal processing method capable of restraining quickly and firmly a direct current voltage, without depending on temperature. SOLUTION: An analog sensor signal is amplified by a neoamplifier 402. The amplified analog sensor signal is measured and compared with a threshold value. The direct current voltage is generated as a function of a difference between the amplified analog sensor signal and the threshold value. A composition signal is generated from the analog sensor signal and the direct current voltage. The composition signal is amplified and an output signal is output. COPYRIGHT: (C)2008,JPO&INPIT
