External TVS diodes can be used to supplement the internal clamping diodes of ICs. Surge ability of silicon TVS diodes are related to size. External TVS diodes can be 10x larger than internal clamping ...
And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...
SPICE circuit simulations are a powerful design tool to analyze a system's immunity against conducted EMI surge voltages. SPICE can serve as a valuable tool to validate and optimize the performance of ...
