Abstract :
We present about a pH sensor, which is capable of measuring high sensitivity using charge transfer technique. The sensitivity of pH was obtained 1130 mV/pH by charge accumulation operation. The proposed pH sensor using charge transfer technique is possible to increase a sensing signal without an extra amplifier. It is expected that charge transfer type pH sensor increases sensitivity and decreases random noise.
