摘要

本研究的目的是提出一种电子可调谐仪器放大器的新设计。所提出的电路采用电流模式设计方法。提出的电流模式仪表放大器采用单个Extra-X电流控制电流输送机(EX-CCCII)和接地电阻。该电路设计非常简单，适合集成电路。由于电路的高输出阻抗，它可以与其他电流模式电路级联而不需要缓冲器。此外，该电路可通过EX-CCCII的偏置电流进行电子调谐。所提出的仪表放大器具有良好的频率性能，具有宽带宽的差分增益和CMRR。分析了非理想性对EX-CCCII及其寄生因子的影响。为了验证所提出的仪表放大器，使用CADENCE VIRTUOSO SPECTRE模拟器使用0.18µm CMOS技术参数进行了各种仿真。

Single EX-CCCII based electronically tunable current mode instrumentation amplifier

The purpose of this study is to present a new design for an electronically tunable instrumentation amplifier. The current-mode design approach is used for the proposed circuit. The proposed current-mode instrumentation amplifier employs a single Extra-X Current Controlled Current Conveyor (EX-CCCII) and a grounded resistor. This circuit design is very simple and suitable for IC integration. Because of the circuit's high output impedance, it can be cascaded with other current-mode circuits without the need for a buffer. In addition, this circuit is electronically tunable with the bias current from EX-CCCII. The proposed instrumentation amplifier provides good frequency performance with a wide bandwidth for differential gain and CMRR. The effects of non-idealities of EX-CCCII and its parasitic elements are also analysed. To validate the proposed instrumentation amplifier, various simulations are performed with the CADENCE VIRTUOSO SPECTRE simulator using 0.18 µm CMOS technology parameters.

期刊介绍： Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
