abstract: In this work, a 12-bit ADC with three types of calibration is proposed for high speed security applications as well as a precision application. This converter performs for both applications because it satisfies all the necessary specifications such as minimal device mismatch and offset, programmability to decrease aging effects, high SNR for increased ENOB and fast conversion rate. The designed converter implements three types of calibration necessary for offset and gain error, including: a correlated double sampling integrator used in the first stage of the ADC, a power up auto zero technique implemented in the digital code to store any offset and subtract out if necessary, and an automatic startup and manual calibration to control the common mode voltages. The proposed ADC was designed in Intel’s 10nm technology. This ADC is designed to monitor DC voltages for the precision and high speed applications. The conversion rate of the analog to digital converter is programmable to 7µs or 910ns, depending on the precision or high speed application, respectively. The range of the input and reference supply is 0 to 1.25V. The ADC is designed in Intel 10nm technology using a 1.8V supply consuming an area of 0.0705mm2. This thesis explores challenges of designing a dual-purpose analog to digital converter, which include: 1.) increased offset in 10nm technology, 2.) dual application ADC that can be accurate and fast, 3.) reducing the parasitic capacitance of the ADC, and 4.) gain error that occurs in ADCs. / Dissertation/Thesis / Masters Thesis Electrical Engineering 2017
