초록

An FET type urea sensing device has been developed using the ISFET and platinum reference electrode and by employing the differential amplification. The performance characteristics of the fabricated sensor show a good linearity in the urea concentration range of $5{\times}10^{-5}$ to $10^{-3}$g/ml and a stable response.
