![]() The DA accuracy can be arbitrary set by configuring the number of bits in the DA capacitor digital-to-analog-converter the amplifier gain is decoupled from the transistor intrinsic gain which is suitable for scaled CMOS integration. DA cancels out all errors (i.e., gain error, nonlinearity, incomplete settling, power supply noise, and thermal noise) of the low-gain amplifier by feedback based on successive approximation. In this paper, we introduce a digital amplifier (DA) technique to realize power-efficient and accurate amplification in scaled CMOS. Prior works focused on gain calibration techniques to mitigate the use of low-gain amplifiers, in return of system complexity and prolonged startups. However, realizing such an amplifier in scaled CMOS is challenging due to the worsened transistor characteristics. ![]() ![]() ![]() To realize high-resolution pipelined and pipelined-SAR analog-to-digital-converters (ADCs), an accurate residue amplifier is necessary. ![]()
