Abstract

A practical realization of a tunable floating capacitance multiplier using commercially available integrated circuits, namely LT1228 is proposed. The synthetic capacitor utilizes only two IC LT1228s along with two passive components (one resistor and one capacitor). The capacitance multiplication factor is electronically controllable through the transconductance gain of the LT1228. The effects of non-ideal transfer gains and parasitic elements of the LT1228 on the circuit performance have been evaluated in detail. The applicability of the proposed floating capacitance multiplier as a second-order band-pass filter is also presented. The claimed theory is verified by several PSPICE simulations and experimental test results.

用市售集成电路lt1228实现实用浮动电容倍增器

提出了一种利用市售集成电路LT1228实现可调谐浮动电容倍增器的方法。合成电容器仅利用两个集成电路lt1228以及两个无源元件(一个电阻和一个电容器)。电容倍增系数可通过LT1228的跨导增益进行电子控制。详细分析了LT1228的非理想转移增益和寄生元件对电路性能的影响。提出了浮动电容乘法器作为二阶带通滤波器的适用性。该理论已通过PSPICE仿真和实验测试结果得到验证。
