Power efficient hearing aid |
摘要 |
A power efficient hearing aid uses a programmable biasing technique to set the quiescent operating points of amplifiers used by the hearing aid to avoid excessive power usage by the hearing aid. The hearing aid also includes power supply circuitry which develops +1.25 volts and -1.25 volts relative to ground from a single +1.25 volt source. The hearing aid also conserves power by selectively disabling low frequency signal processing channels in the presence of relatively large amplitude ambient noise.
