Claim 1:
2. The method of claim 1, further comprising:
sequentially connecting a second fixed voltage and an output of a second digital to analog converter to an input of a second magnetic tunnel junction device, using a third single pole double throw analog switch;
sequentially connecting a V+ output and a V− output of the second magnetic tunnel junction device to an input of a second band pass filter using a fourth single pole double throw analog switch, wherein the third single pole double throw analog switch is configured such that the second fixed voltage is connected to the input of the second magnetic tunnel junction device when the V+ output is connected to the input of the second band pass filter, and the second digital to analog converter is connected to the input of the second magnetic tunnel junction device when the V− output is connected to the input of the second band pass filter; and
modifying the output of the second digital to analog converter such that an output of the second band pass filter produces an unsaturated sine wave wherein
measuring the current passing through the current carrying conductor comprises measuring the current passing through the current carrying conductor using the second magnetic tunnel junction device after modifying the output of the second digital to analog converter.
