Title:
ION CONCENTRATION DISTRIBUTION MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/151012
Kind Code:
A1
Abstract:
This ion concentration distribution measuring device is provided with a unit detecting portion 10m,n which outputs an electric charge in an amount corresponding to an ion concentration, and an integrating circuit 20n which outputs a signal value corresponding to the amount of electric charge output from the unit detecting portion. The unit detecting portion 10m,n includes a MOS transistor 11, an ion sensitive portion 12, a first capacitor portion 13 and a transfer switch 14. The integrating circuit 20n includes an amplifier 21, a second capacitor portion 22 and a reset switch 23. By this means, an ion concentration distribution measuring device that is less susceptible to the effects of noise is realized.
