  • Digital current sensor for on-die switching voltage regulator
    Patent number: 10348200
    Abstract: Described is an apparatus which comprises: an output node; a capacitor; an inductor having a first terminal coupled to the output node, and a second terminal coupled to the capacitor; a bridge to receive an input power supply and to generate a switching voltage signal at the output node; and a current sensor to determine slope of the switching voltage signal on the output node.

  • Low power current sensor
    Patent number: 9638720
    Abstract: Described is a current sensor comprising: a main resistive branch having a target device coupled to a load at a first node; a replica resistive branch having a replica device which is a replica of the target device, the replica device coupled to a current digital to analog converter (DAC) at a second node; and an analog to digital converter (ADC) coupled directly or indirectly to the first and second nodes, the ADC to generate an output coupled to the current DAC.
