Hi all,
This is my very first post and I am so glad that I found this wonderful community. Currently I am developing some wireless sensors that makes use of the circuitry attached below. This is an ECG sensor which I adopted from an experiment in Hardvard University. However, since in developing something really small, space is of concern. I am trying to reduce the circuitry below and would love to accept suggestions or solutions on how I can do that.
One of the solution I had in mind was to remove the voltage divider (1.5V) which was used as a voltage rail so the ECG signal would not exceed 1.5V. Please help. Thanks
Secondly, from the diagram circled A,B and C, is there a way that I can calculate these values accurately? I cant seem to recall how to calculate the gains of circles marked A and B. Thanks again.
