Hi, for my college thesis I'm trying to implemet ecg amplifer without any external components(!!!), and I need some help. I'm using PSoC 5lp cy8ckit-059. I found this picture of ecg amplifier circuit somewhere (attached 1st pic). First two PGAs are instrumentation amplifier. I also found that for instrumentation amplifier PGA gain has to be 2. (2nd pic). But I have to achieve amplification somewhere aroud 1000. So if i put the 3rd PGA (after filters) G=50, with first two PGAs (before filter) G=2, where can i squeeze the rest needed amplificaiton=5 (or 4) so the whole amplification is 2*2*50*5=1000 (or 2*2*50*4=800)?
Thank you

How should I configure DelSig_ADC if I want to measure ECG signal?
So, input mode-differential, resolution-20, and what about other parameters (such as input range etc)?
Thank you very much in advance

I did it exactly as odissey1 says
Perhaps it will help you, but this is a very old project:
for PSoC Creator 1.0 : ECG_PGA.zip
