The new droopy passive lowpass filter is not a sharp active Butterworth Sallen and Key type.here is the final circuit..check it please and if you see something unproper tell me
Your schematic has a grey background, is covered with dots, has big spaces which makes it huge and was saved as a very fuzzy JPG file type.
Why not make the ECG circuit that is shown on the datasheets for intrumentational amplifier ICs?so i don't need the Noise Cancellation?
Maybe you mean, "adaptive"? ECG circuits use the common-mode cancellation opamp.how about adaptife noise cancellation?
It was posted before. It takes the common-mode DC and low frequency AC from the instrumentation amp and feeds the patient's right leg like opamps A1 and A2 in this ECG circuit taken from the datasheet of an instrumentation amp:so how i can make the common-mode cancellation opamp?
You are going around in circles.how i can make the common-mode cancellation opamp in my circuit (see attachment)?
