基于跨导运算放大器的多模多频可重构滤波器的设计
Design of multi-mode multi-frequency reconfigurable filters based on OTA
摘要
Abstract
The design of the filters in multi-mode multi-frequency RF front-end receivers is studied.To make the filters have various work modes and functions to reduce their size and power consumption, and overcome the inconven-ience of electrical tuning and the low linearity to enlarge their applying scope, a method for design of multi-mode multi frequency reconfigurable filters based on operational trans-conductance amplifier ( OTA) is proposed.It can realize different operating modes in one filter topology by setting the suitable switch array, and different functions can be performed by selecting suitable output terminal.Moreover, the designed filters have the advantages of high linearity and easiness for integration.The filter designed using this method has the simple circuit and the higher hardware reuse rate, and is easy to integrate, and the experiment proved its versatility and higher linearity, so it is suitable to monlithic integrated multi-mode multi-frequency receivers.关键词
