OTA Model Used in Active-Passive Filter for Lowering Power Consumption
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 11
Abstract
Biomedical signals are usually of 10-mHz to 100-Hz frequency range. Designing of these low power consumption filters has many applications in biomedical signal processing and their interfacing with sensors. The performance of these filters designed by the use of passive components degrades at audio frequencies and the required resistance and inductance values calculated from the mathematical expression are very difficult to meet from the market. In this we study the realization of Passive Filters into Active Filters using Operational Transconductance to solve the problem of power consumption.
