摘要：

This paper describes an analog baseband for single-chip 2G/3G/4G MIMO transceivers. By capacitor sharing technique and log tuning, the RX filter is programmable to set fc from 0.1 to 14MHz with 2% accuracy with 93dB gain range which is linear-in-dB. The TX filter suppresses DAC images and noise for Saw-less with constant or ramping envelope. A digital calibration adjusts fc, Q, and DC offset. The filter implemented in 65nm CMOS, occupies 2.79mm(2), and consumes 7.3/8.4/10.2mW with 1.2V supply for 2G/3G/4G, respectively. This chip is in mass production for handheld products.
