    摘要: The invention relates to an integrated microphone/amplifier unit, in particular for a hearing aid, which is largely insensitive to interference signals such as, for instance, could be caused by GSM telephone apparatuses because capacitive couplings are arranged between the amplifier output and ground, and between the feed and ground. These capacitive couplings are made by the thick-film technique and can be provided with a separate ground connection. In one embodiment the capacitive couplings comprise capacitors, of which the output and feed connections themselves form part. In another embodiment the capacitive couplings comprise capacitors that are formed on the back of a carrier.
