Design of Reconfigurable Passive Noise Shaping SAR Analog-to-Digital Converter
With the advancement of industrial technology,the requirements for accuracy and power consumption of analog-to-digital converters are increasing.Given the excellent performance of noise shaping analog-to-digital converters,this paper proposes a reconfigurable 18 bit noise shaping successive approximation register analog-to-digital converter(SAR ADC)circuit,which uses SMIC 40 nm technology.The ideal model is verified through simulation,aiming to explore its potential applications in fields such as the Internet of Things.The experimental results show that the analog-to-digital converter achieves a 17.4-bit effective bit rate at a throughput of 1 MS/s under standard configuration,demonstra-ting high-precision characteristics.By reconfiguring,it can switch to low-power high-speed mode,increasing the through-put to 5 MS/s while maintaining an effective accuracy of 11.99 bits,balancing performance and power consumption.This reconfigurable design not only meets the requirements of high precision and low power consumption,but also can be widely applicable to various data sampling scenarios due to its flexibility,providing an innovative solutions for high-performance analog-to-digital converter design in fields such as the Internet of Things.
