摘要

提出了基于电流差跨导放大器(CDTA)和电压差跨导放大器(VDTA)的频率敏捷滤波器。提出的敏捷滤波器配置采用接地无源元件，因此适合集成。采用0.25 μm TSMC CMOS技术模型参数进行了广泛的SPICE仿真，以进行功能验证。从功耗、信噪比(SNR)和最大输出噪声电压等性能参数对两种器件进行了比较。

Design of CDTA and VDTA Based Frequency Agile Filters

This paper presents frequency agile filters based on current difference transconductance amplifier (CDTA) and voltage difference transconductance amplifier (VDTA). The proposed agile filter configurations employ grounded passive components and hence are suitable for integration. Extensive SPICE simulations using 0.25 μm TSMC CMOS technology model parameters are carried out for functional verification. The proposed configurations are compared in terms of performance parameters such as power dissipation, signal to noise ratio (SNR), and maximum output noise voltage.
