On The Tuning Performance of an Active RF Bandpass Filter
Journal Title: Acta Technica Napocensis- Electronica-Telecomunicatii (Electronics and Telecommunications) - Year 2008, Vol 49, Issue 3
Abstract
The paper describes a new principle of independent frequency and quality factor tuning suitable for simulated inductors based active RF filters. The method makes use of two dc decoupled negative resistances in order to avoid frequency and quality factor inter–dependency. A differential architecture is studied and several considerations regarding the tuning capability and stability behavior are presented. The target application is a multi–standard active bandpass filter envisaging wireless transceivers.
