Abstract

A novel CMOS low-voltage positive current conveyor of second generation is described in this paper. This solution allows almost rail-to-rail input and output operation and a high driving capability, thanks to the adoption of a class AB current output stage. A prototype was fabricated in a 0.35-μm technology and experimentally tested. Using a 1.5-V supply, the circuit exhibited an input resistance of lower than 100 Ω at the input terminal and a better than ±0.9 mA current drive capability, which was about 45 times the quiescent current in the output branch. Good frequency performance was also obtained.
