ELECTRONIC-CIRCUIT-DESIGN PRINCIPLES FOR PARAMETER CONTROL OF ISFETS AND RELATED DEVICES

With the development of semiconductor transducers, such as i.s.f.e.t.s and related devices, a new class of transducers has been introduced in which the actual transducer function is integrated with part of the corresponding electronic circuitry. In the paper the transducer is therefore considered as being a new electronic component instead of being seen by the classical approach, in which the transducer and the electronic circuit are simply series connected. This view appears to result in unique possibilities for stabilisation and control of transducer characteristics. This is illustrated in the paper with respect to the effects of internal series resistances and the temperature sensitivity of i.s.f.e.t. devices. © 1979 IFMBE.
