Small-area DAC capacitor array for SAR type ADCThe utility model relates to a small-area DAC capacitor array for a SAR type ADC. The small-area DAC capacitor array corresponds to a C-2C trapezoid capacitor network circuit and is formed by multiple repetition units which are parallelly ...
本文提出一种低功耗、高精度、低复杂度的SAR ADC(逐次逼近模数转换器)的DAC电容阵列开关切换方案.每一个电容只连接了两种参考电平,因此降低了逐次逼近逻辑电路和电容驱动电路的复杂度.在前两次开关切换过程中不需要消耗能量,并且是单边切换,有效的降低了开关能量的消耗.DAC电容阵列分为完全相同的两部分,即MSB电容阵...
These sensors are usually passive or supplied by batteries and are usually a mixed-signal circuit. Analog to digital converter (ADC) is a core element in the sensor, and the power consumption of occupies a considerable part of the whole sensor. SAR ADC is a good candidate for the sensor ...

The high and nearly constant linearity is enabled by an improved bootstrap circuit for the input switch, while the high sampling rate, the highest among recently published >34-dB SNDR single-channel SAR ADCs, is accomplished by a triple-tail dynamic comparator and a unit-switch-plus-cap (US...

Not that I am aware of without using an voltage monitoring external circuit. The VDD must be less than 0.7 V for at least 1 ms for the POR to occur in the DAC so that would need to be monitored if you expect this supply condition to happen. ...
