Abstract

Disclosed herein, among other things, are systems and methods for improved circuit design for hearing assistance devices. One aspect of the present subject matter includes a hearing assistance device configured to compensate for hearing losses of a user. The hearing assistance device includes a substrate and an interposer embedded into the substrate to form a system in package module. According to various embodiments, the interposer includes one or more integrated circuits (ICs) on the interposer, the one or more ICs configured to provide electronics for the hearing assistance device.

Claims (15)

1. A hearing assistance device, comprising:

a substrate; and

an interposer embedded into the substrate to form a system in package module sized to fit in an ear of a wearer,

wherein the interposer includes one or more active flip chip integrated circuits (ICs) and one or more integrated passive devices attached to the interposer prior to embedding, the one or more ICs configured to provide electronics for the hearing assistance device.

2. The hearing assistance device of claim 1 , wherein the interposer includes silicon.

3. The hearing assistance device of claim 1 , wherein the interposer includes glass.

4. The hearing assistance device of claim 1 , wherein the interposer includes an organic material.

5. The hearing assistance device of claim 1 , wherein the hearing assistance device includes a cochlear implant.

6. The hearing assistance device of claim 1 , wherein the hearing assistance device includes a hearing aid.

7. The hearing assistance device of claim 6 , wherein the hearing aid includes an in-the-ear (ITE) hearing aid.

8. The hearing assistance device of claim 6 , wherein the hearing aid includes a behind-the-ear (BTE) hearing aid.

9. The hearing assistance device of claim 6 , wherein the hearing aid includes an in-the-canal (ITC) hearing aid.

10. The hearing assistance device of claim 6 , wherein the hearing aid includes a receiver-in-canal (RIC) hearing aid.

11. The hearing assistance device of claim 6 , wherein the hearing aid includes a completely-in-the-canal (CIC) hearing aid.

12. The hearing assistance device of claim 6 , wherein the hearing aid includes a receiver-in-the-ear (RITE) hearing aid.
