Abstract :
We propose a very simple current copier in which the accuracy of the circuit operation is improved significantly by reducing the effect of charge injection and by eliminating the parasitic capacitive coupling. This improvement is achieved without introducing any matching devices or requiring any complementary clock signals. The proposed current copier can be implemented using a standard CMOS process without any technological restrictions. Some applications of the proposed current copier are suggested
