| Abstract(in English) | Not only organic disease also Hearing disability is critical issue in aging society. In recent years, the advancement of the signal processing technology enables assistance with a digital hearing aid. Hearing aid requires to consist of small size A/D and D/A converters, and run by low power and with wide dynamic range. In this study, Full digital D-class Amprefire was adopted for reducing analog circuit. Typical Class D amplifier requires external LC filter to remove the PWM carrier frequency , however, Mini Canal Hearing Aids doesn't have the volume in which the filter can be mounted. The Class D amplifier system that can drive receiver highly effective without filter was acheived. |
