摘要

本文报道了两种基于差分电压Extra-X电流控制电流输送机(DV-EXCCCII)的滤波电路。第一个提出的电路是一个电压模式一阶通用滤波器，它采用一个DV-EXCCCII，一个电阻和一个接地电容器。该电路可以实现所有标准的一阶滤波器，即低通、高通和全通滤波器。第二个提议的电路是一个一阶多模通用滤波器，它采用一个单一的DV-EXCCCII。该电路可以用一个电容实现电流模式、电压模式和跨导纳模式的滤波。然而，跨阻抗模式通用滤波器是通过附加电阻实现的。此外，该滤波器可通过DV-EXCCCII的偏置电流进行电子调谐。在0.18µm UMC CMOS技术参数下，利用CADENCE VIRTUOSO工具的SPECTRE模拟器对所提出的滤波电路进行了验证。

First order universal filters employing single DV-EXCCCII

ABSTRACT This paper reports two filter circuits based on Differential Voltage Extra-X Current Controlled Current Conveyor (DV-EXCCCII). The first proposed circuit is a voltage-mode first-order universal filter that employs one DV-EXCCCII, one resistor, and one grounded capacitor. This circuit can realise all standard first-order filters, that is, low-pass, high-pass and all-pass filter. The second proposed circuit is a first-order multimode universal filter that employs a single DV-EXCCCII. This circuit can realise filter in current-mode, voltage-mode and trans-admittance mode with a single capacitor. However, a trans-impedance mode universal filter is realised with an additional resistor. Furthermore, the filter is electronically tunable with the bias current of DV-EXCCCII. The proposed filter circuits are verified using the SPECTRE simulator of CADENCE VIRTUOSO tool in 0.18 µm UMC CMOS technology parameters.
