AbstractThis paper presents a 2.3 GS/s 12-way time-interleaved pipelined-SAR ADC achieving 1.1 GHz input bandwidth with 47.4 dB signal-to-noise distortion ratio (SNDR). Here, we propose a hierarchical interleaving with passively shared sub-sampling front-end to eliminate the timing skews, thus avoiding the timing calibration for design simplicity as well as better area and power efficiency. To provide a fast signal transfer with good power efficiency to the sub-ADCs, the power and bandwidth trades off by using the passive sharing or active buffers are analyzed according to our developed mathematic model. The analysis is based on two scenarios: Noise and matching limited sampling. Moreover, we propose a boosting-capacitor-sharing technique to enhance the compactness of the time-interleaved bootstrapped sampling front-end, which is particularly critical when omitted the time calibration in this design. Measurement results on a 65 nm CMOS prototype operated at 2.3 GS/s and 1.2 V supply show 31 mW total power consumption with a SNDR of 47.4 dB @Nyquist leading to a FOM of 69 fJ/conv.step.
