Abstract: A buffer circuit includes a first current generating unit, a second current generating unit, a comparator, a differential driving unit, and an inverter. The first current generating unit outputs a first current corresponding to a reference voltage and a magnitude of which is adjusted by a feedback voltage. The second current generating unit generates a limit current corresponding to an input limit voltage, a magnitude of which is adjusted by the feedback voltage, and which has a value corresponding to a half of the limit current. The comparator generates a feedback voltage by comparing the first and second currents. The differential driving unit generates an internal current by comparing an input voltage signal and a reference voltage, and adjusts an internal current based on the feedback voltage such that an upper limit value and a lower limit value of the internal current are symmetrical with respect to 0. The inverter generates an output current by reversing the internal current based on a power voltage. Accordingly, a pull-up current supply capacity and a pull-down current supply capacity may be provided regardless of a magnitude of a voltage of a power source.

Abstract: The present invention relates to a blood glucose measurement sensing module having an automatic inspection function, and to a continuous blood glucose measurement device using the same. To extract a bodily liquid, only a needle is in vivo inserted, and the bodily liquid is transferred by a transferring pump. Then, a blood glucose concentration is measured in a measurement sensor disposed in vitro. The measurement sensor is not disposed in vivo, so an instable phenomenon of a sensor caused by inflammation, granuloma, and blood clot occurring in vivo due to in vivo insertion can be prevented. Also, the operation state of the sensor is stably maintained, and accuracy in a blood glucose concentration measurement result can be improved. An inspection solution is supplied to the measurement sensor at regular periods, and a measurement value with respect to the inspection solution is compared to a standard blood glucose concentration value of the inspection solution. Thus, a measurement value of the measurement sensor is compensated and calculated. Accordingly, inspection is automatically performed without needing a step of extracting blood from the end of a hand through a separate blood-collecting blood glucose measurement device so as to verify accuracy of the measurement sensor. Accordingly, pain and repulsion during a blood extracting step are removed, and blood glucose measurement sensing module can be more conveniently used. Also, a more accurate measurement value can be calculated through compensated calculation of the measurement value by using a compensation solution.
