| Summary: | 碩士 === 中原大學 === 電子工程研究所 === 99 === One configuration for realizing voltage-mode multi-function filters and another configuration for realizing current-mode multi-function filters each using two current-feedback amplifiers (CFAs) are presented. The proposed voltage-mode circuit exhibits simultaneously lowpass, bandpass and highpass filters. The proposed current-mode circuit also exhibits simultaneously lowpass, bandpass and highpass filters. The proposed circuits offer the following features: no requirements for component matching conditions; low active and passive sensitivities; employing only grounded capacitors and the ability to obtain multi-function filters from the same circuit configuration.
