This paper presents a tutorial review of the current-mode approach to analogue electronic circuit design, in particular some of the author’s own research over the past decade covering the development of a new generation of technology specific current-mode analogue signal processing. In this paper various technologies are represented with key current-mode building blocks ranging from current-conveyors, current-feedback operational amplifiers, linear transconductance amplifiers to applications ranging from current-mode active filters to low-noise current-mode optical preamplifiers. Advantages, future trends and perspectives of the current-mode approach are highlighted throughout the paper. The theoretical basis for many of the examples dates back many years but it is only recently due to advances in process technology that many of these techniques have now become a practical reality.

Noise Measurements

ABSTRACTThe series resistance limits the linearity of photodiodes and decreases the efficiency of solar cells. It is usually determined from IV-measurements for moderate and high forward current density. This method, however, provides only partial information about Rs, since the series resistance depends on the operating point. An alternative method is based on noise measurements. System noise of the measuring system with a low-noise current-voltage converter has been investigated. A new method for extraction of photodiode series resistance from noise measurements is suggested. Noise measurements are carried out for a-Si:H pin diodes. The series resistance of an amorphous pin diode has been extracted for different operating conditions using the new measurement method.
