AM Antenna Requirements
1: Effective Inductance of antenna seen by AMI pin needs to be
between 180 uH and 600 uH
2: Effective Quality Factor (Ql) of antenna higher the better, but you get
the diminishing return beyond 150 because the on-chip capacitor Qc
is about 100 at 1MHz
3: Effective terminal stray capacitance seen by AMI by the antenna
should be small, our recommended antennas are in the 8pF range.
