A 1-V 10-bit successive approximation ADC is proposed. The fully differential architecture can suppress the noise effectively and allow a rail-to-rail input voltage range. The settling time of the preamplifier of the comparator becomes nearly two times by using a self-timed bit-cycling technique. In addition, the component will shut down when the conversion is finished. Therefore, the power consumption can be reduced. This successive approximation ADC with a 1-V supply voltage has been design in 0.18-μm CMOS process without low threshold MOS devices. The SNDR is 61.73 dB with the input frequency of 20.04 kHz and sample frequency of 200 kHz. The INL and DNL are between ±0.3LSB, and total power consumption without biasing circuit is 13-μW. FOM of the pre-layout simulation achieves 0.067 (pJ/conv.) without accounting biasing circuit. Bin-Da Liu 劉濱達 2008 學位論文 ; thesis 69 en_US |
