This paper presents a dual output resistance tunable current controlled current conveyor (DO-RTCCCII). In the existing current conveyor the change in bias current is required to alter the design parameter R_x which is the intrinsic resistance of input X terminal. This variation changes the internal dc bias conditions such as saturation margins as well as total power consumption of the block. A resistance trimming block is added at X terminal which is controlled by some programmable bits. The usage of programmable bits helps to achieve the desired response without changing bias current, dc operating point and total power consumption. The port relationships of the DO-RTCCCII block are checked and the circuit and design parameters of current follower, voltage follower are analyzed. The operation of filter circuit is also included to illustrate usefulness of the proposal. The circuit has been designed and simulated using 28 nm CMOS bulk technology model parameters on Cadence Virtuoso/AMS environment (eldo simulator) using 0.75 V supply voltage and results have been verified with post layout netlist.

本文提出了一种双输出电阻可调电流控制电流传送器（DO-RTCCCII）。在现有的电流输送机中，需要改变偏置电流以改变设计参数R _x这是输入X端子的固有电阻。这种变化会改变内部直流偏置条件，例如饱和裕度以及模块的总功耗。在X端子处添加了一个电阻修整块，该块由一些可编程位控制。可编程位的使用有助于在不改变偏置电流，直流工作点和总功耗的情况下获得所需的响应。检查DO-RTCCCII模块的端口关系，并分析电流跟随器，电压跟随器的电路和设计参数。滤波器电路的操作也包括在内以说明该建议的有效性。该电路已在Cadence Virtuoso / AMS环境（eldo模拟器）上使用0的28 nm CMOS批量技术模型参数进行设计和仿真。
