摘要

提出了一种新型的基于跨线性电路的CMOS电子可调谐电流输送机(ECCII)，具有低功率电压(±1.2 V)、连续可编程电流增益和高线性宽调谐范围的特点。通过直流偏置电流的比值可以精确地控制输送机的电流传递比。采用0.35 μ m CMOS工艺模型的HSPICE仿真结果证实了所提出的ECCII在线性度、频率响应和可调性方面的良好性能。

A new CMOS electronically tunable current conveyor based on translinear circuits

A new CMOS electronically tunable current conveyor (ECCII) based on translinear circuits is presented, with low power voltage (plusmn1.2 V) and continuous programmable current gain and highly linear wide tuning range. The current transfer ratio of the conveyor can be accurately controlled by the ratio of the DC bias currents. HSPICE simulation results using 0.35-mum CMOS process model confirm the expected good performance of the proposed ECCII in terms of linearity, frequency response and tunability.
