Title: Method for processing output signal of semiconductor bio sensor
Inventor: KANEYOSHI AKIO
IPC: G01N27/414
Filed: 1991-05-13
Abstract: PURPOSE:To prevent a sensor output from being affected by a small chance in speed for obtaining concentration of a substrate to be measure by performing curve regression approximation of a differential waveform after a sensor output signal is filtered and then integrating it. CONSTITUTION:In a sensor output which is input after A/D conversion, noise components are eliminated by a digital filter and its differential value is calculated by a difference in reference to a data which is input immediately before. This operation is performed until a time C before the sensor output reaches a stationary state. Then, a maximum differential value between a time A and the time C is obtained and this time is set to a time B. A regression approximation according to a second-order curve is performed in an increment period from the time A to the time B, thus obtaining a regression curve. The regression approximation according to an exponential function is performed in a decrease period from the time B to the time C and then a linear approximation is performed assuming that the differential value monotonously decreases between the time C for obtaining the regression curve and the time D where the stationary state is reached. After this, an approximation expression is integrated between the time A and the time D, thus obtaining a predicted final output of the sensor.
