Patent abstract
A CMOS power sensor is disclosed in the present invention. The CMOS power sensor includes a current coil, a high voltage device circuit, and a Hall device. The current coil is fabricated during the process steps of forming gold bumps of a CMOS device. One end of the current coil is connected to a voltage source, and the other end of the current coil is connected to a load. The high voltage device circuit is connected to the voltage source. The Hall device is connected to the high voltage device circuit and induces a Hall voltage in response to the magnetic field generated by the current coil.
