Abstract :
This paper presents alternative current copiers with a negative feedback approach, in which a simple negative-gain amplifier is employed. The proposed copier offers a number of salient features such as simple structure, high stability, fast settling time, high accuracy, and low power supply voltage. Thus the proposed copiers are well suited to the low power current-mode signal processing applications
