摘要

This paper presents a new low power Current Conveyor II (CCII). The proposed circuit uses a 0.4 V single ended supply. The advantages of the proposed current mode readout circuit are threefold. Firstly, the proposed circuit provides extremely low power consumption while operating all MOSFETs in the subthreshold region providing the highest energy efficiency. Secondly, Self cascode technique is used to increase the gain of the differential amplifier to 65 dB. Finally, it is based on standard CMOS technology which can be easily used in VLSI circuits. Near perfect voltage/current tracking up to 1.25 / 0.8 MHz was achieved while consuming 1.7 mu W.
