发明名称 IMPROVED AMPLIFICATION CIRCUIT AND HEARING AID
摘要 <p>Improved amplification circuits and hearing aids that can utilize such amplification circuits are provided. In an embodiment, for example, an amplification circuit includes: a first sub circuit configured to create a voltage drop when a supply voltage is above a first voltage; and a second sub circuit configured to create a reverse voltage drop when the supply voltage is below a second voltage, wherein the first and second sub circuits operate to maintain idling current within a range. Certain embodiments of the present technology also provide hearing aids that include removable dampers.</p>
