New 1.5-V CMOS second generation current conveyor based on wide range transconductor
نویسندگان
چکیده
This paper presents a novel CMOS low-voltage and low-power positive second-generation current conveyor (CCII+ ). The proposed CCII+ uses two n-channel differential pairs instead of the complementary differential pairs; i.e. (n-channel and p-channel), to realize the input stage. This solution allows almost a rail-to-rail input and output operation; also it reduces the number of current mirrors needed in the input stage. The CCII+ is operating at supply voltages of ±0.75 V with a total standby current of 133μA. The application of the proposed CCII+ to realize a MOS-C second order maximally flat low-pass filter is given. PSpice simulation results for the proposed CCII+ and its application are given.
