ABSTRACT:
The invention relates to an automatic reset circuit for detecting much faster transient voltage variation between the supply voltage (VDD) and the electric ground (GND) of an electric system with noise and disturbance. The automatic reset circuit of the invention includes a plurality of detecting units, a plurality of voltage-couple devices connected with the detecting units, and a decision unit with an output port. The decision unit and the voltage-couple devices are also connected. The automatic reset circuit of the invention can detect nanosecond transient voltage variation between the supply voltage and the electric ground, and a reset is then enabled for protecting the inner circuits and surviving the normal operations of the electric system.
