摘要: | A 10-bit 50-MS/s reference-free low power successive approximation register(SAR) analog-to-digital converter(ADC) is presented.An energy efficient switching scheme is utilized in this design to obtain low power and high frequency operation performance without an additional analog power supply or on-chip/off-chip reference. An on-chip calibration DAC(CDAC) is implemented to cancel the offset of the latch-type sense amplifier(SA) to ensure precision whilst getting rid of the dependence on the pre-amplifier,so that the power consumption can be reduced further.The design was fabricated in IBM 0.18-μm 1P4M SOI CMOS process technology.At a 1.5-V supply and 50-MS/s with 5-MHz input,the ADC achieves an SNDR of 56.76 dB and consumes 1.72 mW,resulting in a figure of merit(FOM) of 61.1 fJ/conversion-step. |
