A circuit device to prevent electronic equipment or appliance from attenuating, which connect power to equipment or appliance, meanwhile, connect parallelly with serial connected circuit of current limiting resistance and metal oxide film transistor so as to make an anti-attenuation circuit, application of this parallel connected anti-attenuation circuit can reduce AC resistance of whole equipment, signal output by amplifier can conduct metal oxide film transistor, AC noise power contained is filtered by grounding of current limiting resistance and metal oxide film transistor, so that this power provided hasn't noise jamming and components around may not be radiated, therefore, acoustic product can obtain better fidelity, gasoline molecule isn't jammed by noise, and may combust with air effectively but not reduce its combustion efficiency.
