A real-time load current detecting circuit composed of a power supply circuit, a delay circuit, a current sensing circuit, and a current feedback circuit. The power supply circuit is adapted for providing the CPU with a power source. The delay circuit includes a resistor and a capacitor, connected to the power supply circuit. The current sensing circuit includes a comparison circuit connected to the delay and power supply circuits. The current feedback circuit includes a feedback current source and a resistor, connected to the current sensing circuit. The feedback current source is adapted for mirroring a current sensed by the current sensing circuit. In light of this, the current can be accurately monitored and detected and there is hardly inaccuracy for the detection of the current.

Real-time load current detecting circuit for CPU

An electronic device includes: a conductive housing having an upright end wall formed with an opening; a mother board mounted in the conductive housing and having an end that is disposed adjacent to the upright end wall of the conductive housing, and a grounding trace that has a first end portion disposed adjacent to the end of the mother board, and a second end portion distal from the end of the mother board; a connector mounted on the mother board adjacent to the end of the mother board, extending through the opening in the upright end wall of the conductive housing, and having a grounding pin in electrical contact with the first end portion of the grounding trace; and a ground-bridging mechanism disposed adjacent to the first end portion of the grounding trace and bridging electrically the conductive housing and the first end portion of the grounding trace.
