Here I should have specified hopefully the correct pin numbers.īUT. If I understand the INA128 correctly, it has a gain of 1+50k/, which means putting a 47ohm resistor there should give me a gain of a bit more than 1000. if I remove the instamp complex from the schematic and just run the simulator, I get a nice noise and a nice noisy sine wave like I wanted. It's just a DIP-8 package that's easier to do on the breadboard. The choice of INA128 is basically because it's the part I have, but most likely not the one I'll finally end up using. The SPICE model for INA128 I'm using is from TI: If there's something blatantly wrong with it (besides not adding bypass caps, but I don't think I'll need them for simulation), I wouldn't really be surprised. Please note that I'm a newbie to circuit design, KiCad and SPICE simulation.
MACSPICE EXAMPLES MAC
I'm using a M1-processor mac mini which could be a problem regarding ngspice. I'm trying to build an EMG sensor for biofeedback purposes, but I'm having loads of trouble both on the breadboard and on the CAD side as well.
