A high-quality mixed-signal audio codec in 65-nm CMOS

This paper presents the implementation of an audio codec suitable for 3rd generation mobile telecom standards in a state-of-the-art 65-nm CMOS process. The overall design of the codec together with measurement results of key features are presented. The codec is a mixed-signal design, containing A/D and D/A converters, as well as the digital signal processing blocks needed to support them. Buffers capable of driving low-ohmic loads are also included.
