Abstract
The concept of a chemical current-conveyor, or CCCII+, is presented. The device is primarily intended for pH read-out. At its core is an embedded CMOS current-conveyor, type-II, with two ISFETs in the input stage. The CCCII+ is extremely versatile and can easily be configured to give an output voltage, or current, directly proportional to pH value.
