Bulk CMOS integrated circuits which receive power and perform all I/O functions exclusively by means of inductive coupling have been demonstrated. Both layers of metal in a conventional two-level-metal 3-um p-well technology were used to construct on-chip planar coils for sensing and perturbing externally generated magnetic fields in the 100kHz to 10MHz regime. The optimal design uses few, rather than many, coil turns operating at high frequency. The power delivered to one test chip was 0.9 mW at 3V while a second test chip demonstrated inductive low-power bidirectional communication.
