ABSTRACT:
Methods and apparatuses to sense current and voltage in circuits with voltage drop. In one aspect of the invention, a sense circuit includes a first diode, a first resistor and a light emitting diode (LED). The first resistor is coupled to the first diode. The first current is to be directed through the first diode and the first resistor. A first voltage being the sum of the voltages is developed across the first resistor and the first diode. The LED is coupled to the first diode and the first resistor such that the first voltage is to be applied across the LED to sense the first current. The first current is separate from a current flowing through the LED.
