Abstract

In the presented research, the second-generation voltage conveyor (VCII) is used in the design of active capacitance multipliers. In this paper, three positive and one negative lossless grounded capacitance multipliers (GCMs) are designed. All of these GCMs are designed using two VCIIs, one capacitor, and two resistors. There is no need for any passive component matching to implement a GCM. The multiplication factor of GCMs can be set/varied by changing the values of two resistances as per requirement. Considering nonideal constraints, GCMs are analysed mathematically to evaluate the effect of nonideal current and voltage transfer gains on the performance of the proposed GCMs. Also, parasitic analysis is conducted to study the effect of VCII node impedance on the performance of the presented GCMs. The simulation analysis is performed using Cadence Virtuoso in 0.18 µm Silterra Malaysia process design kit (PDK). Additionally, the macro-model of commercially available integrated circuit, AD844, is used to design the proposed GCM-2 to further prove the theoretical findings.

采用VCII的新型无损正/负接地电容乘法器

在本研究中，第二代电压传送器（VCII）被用于有源电容乘法器的设计。本文设计了三个正负无损接地电容乘法器。所有这些GCM都是使用两个VCII、一个电容器和两个电阻器设计的。不需要任何无源元件匹配来实现GCM。GCM的倍增因子可以根据需要通过改变两个电阻的值来设置/改变。考虑到非理想约束，对GCM进行了数学分析，以评估非理想电流和电压传输增益对所提出的GCM性能的影响。此外，还进行了寄生分析，以研究VCII节点阻抗对所提出的GCM性能的影响。使用Cadence Virtuoso在0.18µm Silterra Malaysia工艺设计套件（PDK）中进行模拟分析。此外，商用集成电路的宏模型AD844被用于设计所提出的GCM-2，以进一步证明理论发现。
