Full-Integrated OTA Active Filter Design Based on Similar Matrix
Shuyan Wang · Journal of Tianjin University Science and Technology · 2005
Full-integrated operational transconductance amplifier(OTA)active filter design method is studied and a practical procedure to derive the OTA active filter from the prototype of doubly terminated LC passive filter is presented. The design method is based on similar diagonal matrix and common network theory. The obtained active filter is composed of OTA and ground capacitances and it is convenient for integration. It also has high stability and low sensitivities. An example is given and the simulated results show that the proposed method is suitable for full-integrated monolithic filters realization.
