该论文提出了一款用于助听器应用的1V 3mA 2.4GHz无线数字音频通信SoC，采用0.18μm CMOS工艺，解决了助听器与外部设备（如手机、PC、电视等）之间的低功耗无线连接需求。
Hearing aids are complex integrated and highly miniaturised systems based on digital signal processor and wireless communication chips. There is a growing need for wireless connectivity between hearing aids and external devices such as cellular phone, PC, sound players (TV, radio, car navigation), remote microphones or even alarm systems. Assistive listening devices based on miniaturized FM receivers [1] operating around 200MHz have been in use for more than 15 years by hearing impaired people. A wireless microphone worn by the speaker (e.g. the teacher in a classroom) captures the speaker’s voice clearly and transmits it directly into the hearing aids. Assistive listening devices are essential for increasing speech understanding in noisy situations such as a
