It includes a diﬀerence ampliﬁer, an integrator, and a comparator with feedback loop that contains a 1-bit DAC. The DAC acts like a switch that connects the negative input of the diﬀerence ampliﬁer to a positive or a negative reference voltage.

SAR ADCs, the key linearity and speed limiting factors are capacitor mismatch and incomplete digital-to-analog converter (DAC)/reference voltage settling. In this the-sis, a sub-radix-2 SAR ADC is presented with several new contributions. The main contributions include investigation of using digital error correction (redundancy) in DESIGN AND ANALYSIS OF A LOW-POWER 8-BIT 500 KS/S SAR ADC FOR BIO-MEDICAL IMPLANT DEVICES by Ehsan Mazidi The presented thesis is the design and analysis of an 8-bit successive approximation register (SAR) analog to digital convertor (ADC), designed for low-power applications such as bio-medical implants.

There is no clear winner This thesis proposes a two-level time- interleaving topology for realizing such an ADC, comprising front-end time-interleaved sub- rate track-and-holds each followed by a sub-ADC which is further time-interleaved to a slower clock frequency. 2 To meet all the requirements for this application, a 16 BIT, 500KSps successive approximation register (SAR) ADC is designed and presented is this thesis. Master Thesis Project Implementation of a 200 MSps 12-bit SAR ADC Authors: Victor Gylling & Robert Olsson Principal supervisor at LTH: Pietro Andreani Supervisors at Ericsson: Mattias Palm & Roland Strandberg Examiner at LTH: Peter Nilsson Department of Electrical and Information Technology Faculty of Engineering, LTH, Lund University SE-221 00 This thesis presents a pipelined SAR ADC for wireless IEEE802.11n standard which requires a minimum ADC sampling frequency and resolution of 40MHz and 10bits respectively.

A thesis submitted in fulfillment of the. This thesis focuses on the specific implementation of the “Split-ADC” self- calibrating algorithm on a 16 bit, 1 MS/s differential SAR ADC. The ADC can be 9 May 2018 Linearity of SAR ADC is limited by the DAC mismatch error. • DAC calibration improves ADC linearity (using advanced PHD Thesis, 2010. the CAP-DAC in a SAR ADC by reviewing some of the most effective and Franco Manfredi Best Ph.D.

This work studies the architecture in depth, highlighting its main constraints and tradeoffs involving into SAR ADC design. The work researches asynchronous operation of SAR logic and investigates the latest trends for ADC’s analog components – comparator and DAC. 10-bit asynchronous SAR ADC is implemented in CMOS 0.18 µm. Successive approximation register (SAR) analog-to-digital converter (ADC) is a topology of choice in today’s market for medium to high resolution conversions. It typically provides a resolution of 8 to 18-bits with under 5Msps sample rate, which makes it ideal for applications like This thesis shows that a SAR and Sigma-Delta ADC can be integrated with the microcontroller. The measurements show good results, but are not perfect. The ADCs can still be im-proved, depending on the desired design parameters.

integrated SAR ADC with III-V CS (i.e., InGaAs) sampling switch and remaining circuits in CMOS technology. The 6-bit 125 MSps SAR ADC occupies a 0.0225 mm2 chip area, achieves a post-layout simulated peak SNDR of 35.56 dB/35.98 dB and an SFDR of 48.7 dB/53.17 dB for ADCs using a CMOS/InGaAs sampling switch. Successive approximation register (SAR) analog-to-digital converters (ADCs) are known for their outstanding power efficiency as well as good technology scal- ing characteristics. However, since SAR ADCs use a serial conversion algorithm, their low power advantage significantly deteriorates at high sampling frequencies (> 100 MS/s). designing ultra-low power SAR ADCs. This thesis work initially investigates and compares different structures of SAR control logics including the conventional structures and the delay line based controller. Additionally, it focuses on selection of suitable dynamic comparator architecture.
