A 40 nm CMOS analog front end (AFE) supporting HSPA/EDGE multimedia and enhanced audio applications is reported. The AFE consists of hi-fi audio and high-performance peripheral and auxiliary subsystems. Circuit techniques that enable a 200 μA audio RX path and a Class-AB driver with −80 dB THD are discussed. Audio playback and capture paths achieve 105 dB and 85 dB SNR, respectively. [ABSTRACT FROM PUBLISHER] |
