#96430 - is it ground bounce |
in one of my analog circuit operational amplifer (lm324)is used to dectect 800mv threshold voltage arriving at inverting pin irregularly,opamp give right signal only if i touch ground of pcb,when i donot touch ground of pcb it gives false signal is it ground bounce or common mode noise.
