| Outline of Final Research Achievements |
Impedance scaling (IS) circuits based on current feedback theory to realize ultra-low-frequency integrated active filters have been developed for small-sized biomedical electronic devices. The main purpose is to reduce the offset voltages of fully differential filter employing symmetry-type floating impedance scaling (SFIS) circuits. The proposed technique is unifying a common-mode feedback (CMFB) circuits and the SFIS circuit unlike an ordinary way that the CMFB is combined with an OTA or an OPamp. In addition, other synthesizing techniques for low frequency filters with low offset voltages.
