Hi
We are designing a PFC,and we need a good low side current sense amp, the problem is that we got all sort of noise,spikes and crap along the current using this standard low side circuit, we have tested these op-amps, OP07 ,LMV358 and LM358, the OP07 shows better result regarding the noise and spike, but we got lot's of spike, the next stage to the Current sense is another LM358 in comparison mode so we could detect over current and switch of the mosfet,because of spikes and noise our MCU get lot's of over current interrupts, Do you have any idea what's wrong?
