First Claim
1. An electronic device comprising:
- a first node to be coupled to a first antenna;
a second node to be coupled to a second antenna;
a third node to be coupled to a third antenna;
a first comparator coupled with a first input to the first node and with a second input to a second node;
a second comparator coupled with a first input to the first node and with a second input to the third node; and
a third comparator coupled with a first input to the second node and with a second input to the third node, wherein each of the first, the second and the third comparator is configured to compare a first current and a second current at the first input and the second input.
