Abstract :
A time-interleaved pipeline ADC is designed for an 802.11b/Bluetooth dual-mode receiver. Its operation mode can be configured to satisfy the resolution and sampling rate required by each standard. System and circuit level techniques are applied to optimize the ADC power dissipation. An on-line digital calibration scheme is developed to cancel both non-linearity and mismatch in the ADC. The measured dynamic range of the ADC is 60 dB at 44 MS/s and 64 dB at 11 MS/s over the 802.11b and Bluetooth signal bandwidth, respectively. The ADC consumes 14.8 mW in the Bluetooth mode and 20.2 mW in the 802.11b mode.
