    Help with Multiple Feedback Bandpass filter for ECG signal

    I am trying to create a 2 stage Mutiple feedback bandpass filter for a band of Frequenz of 8 to 18hz for ECG Rpeak detection. The 1st stage has cut off frequency band of 4.5 to 13hz and 2nd stage have a band of 10 to 26hz. I am using OPA2338 and working voltage of +v=3.3v and -v=0v. Circuit is...

    ECG EKG lead protection - TVS Diodes

    ECG leads generally see voltages in the range of -5mV to 5mV and a frequency range of .05Hz - 150Hz. We are peripherally stimulating the patients with up to 200v at a frequency of 1kHz elsewhere on the body for about 100mSec and it disrupts our front-end ECG chip. I need to protect the ECG leads...

    LTspice ECG

    Hello. Thank you for clicking on my article. I'm from Korea and a college student. I'd like to find a solution. My circuit simulation speed is too slow. So I want to speed up. I saw what other people did at Google and made it. I want to speed up the simulation. I'd appreciate your help.
