摘要：
In this paper we describe an approach for the design of high-accuracy, high-precision, current mode amplifiers. These circuits take advantage of dynamic element matching (DEM) for compensating the input offset and 1/f noise voltages of the nominally identical (source-coupled) transistor pairs in a second generation current conveyor (CCII). In comparison with high-accuracy, high-precision op amp based amplifiers, the proposed approach is more convenient if the gain of the op amp may not be very high, e.g. due to short channel effects.
