A Reconfigurable 5-to-14 bit SAR ADC for Battery-Powered Medical Instrumentation
IEEE Transactions on Circuits and Systems I: Regular Papers(2015)
摘要
In battery-powered medical instrumentation, the resolution and signal bandwidth of analog-to-digital converters (ADCs) have to be adapted to the needs of the application to avoid power wastage. This paper presents a reconfigurable successive approximation register (SAR) ADC implemented in 130 nm CMOS that resolves 5-14 bit with a maximum achievable effective number of bits (ENOB) of 13.5 using non...
