Patent ID: 8564091

Claim:
A semiconductor package comprising: a first die; a second die; and an inductor arrangement configured to inductively couple the first die and the second die while maintaining electrical isolation between active circuit components of the first die and active circuit components of the second die, wherein the inductor arrangement includes (i) a first inductor circuit of the first die and (ii) a second inductor circuit of the second die, wherein the first inductor circuit comprises: a first bond wire electrically coupled between (i) a first connector of the first die and (ii) a second connector of the second die; a first interconnect electrically coupled between (i) the second connector of the second die and (ii) a third connector of the second die, wherein the second connector, the third connector and the first interconnect are electrically isolated from the active circuit components of the second die; and a second bond wire electrically coupled between (i) the third connector of the second die and (ii) a fourth connector of the first die, and wherein the second inductor circuit comprises: a third bond wire electrically coupled between (i) a fifth connector of the second die and (ii) a sixth connector of the first die; a second interconnect electrically coupled between (i) the sixth connector of the first die and (ii) a seventh connector of the first die, wherein the sixth connector, the seventh connector and the second interconnect are electrically isolated from the active circuit components of the first die; and a fourth bond wire electrically coupled between (i) the seventh connector of the first die and (ii) an eighth connector of the second die, wherein the inductor arrangement is configured to inductively transmit signals between the first inductor circuit of the first die and the second inductor circuit of the second die, wherein the first inductor circuit of the first die is configured to operate as a primary coil of a transformer, and wherein the second inductor circuit of the second die is configured to operate as a secondary coil of the transformer.
