摘要：
在过去的几年里，纳米电路设计领域的进步已经变得比需求更难。低功耗器件大量涌现，电压模式器件和电流模式器件已被证明可以相互替代，以满足不断增长的市场需求。因此，电流传送器已经公平地确立了它们作为重要电路设计元件的独特性。在模拟VLSI设计领域的几年中，我们可以获得的文献引用了大量基于电流传送器的应用元件。类似地，本文提出了一种基于第二代电流控制电流传输器跨导线性电路方案的新型可调谐低功率电压放大器。本文提出的电路建模采用最少的无源元件。这里所示的调谐幅度或电压幅度由两个可变电阻器控制。电流传输器第二代跨导线性电路方案被考虑到实现所提出的可调电压放大器。CCCII的工作原理是低功耗和低电压设计。可调谐电压放大器可用于模拟以及数字信号处理应用中。
英文摘要：
In the past few years, advancements in the field of nano circuit design has become tougher than the demand. Low power devices have emerged tremendously.Both voltage mode aswell as current mode devices have proven alternative to each other for satisfying the demand of the growing market. As such, current conveyors have equitably established their uniqueness as an important circuit design element. The literature available to us during the few years in the field of analog VLSI design, quotes a huge number of application elements based on current conveyors. Likely, in this paper, a new tunable low power voltage amplifier based on the translinear circuit scheme of second generation current controlled current conveyor has been proposed. The modeling of the circuit presented in this paper employs the minimum number of passive elements. The magnitude of the tuning or the amplitude of the voltage presented here, is being controlled by means of two variable resistors. Current conveyor second generation translinear circuit scheme is taken into consideration to implement the proposed tunable voltage amplifier. CCCII works on the outlines of low power and low voltage design. Tunable voltage amplifiers find use in analog as well as in digital signal processing applications.
