HIGH-SPEED SUCCESSIVE APPROXIMATION REGISTER (SAR) ADC DESIGN WITH MULTIPLE CONCURRENT COMPARATORS A Thesis Presented to the Graduate Faculty of Lyle school of Engineering in Partial Fulfillment of the Requirements for the degree of Master of Science in Electrical Engineering by Tao Fu August 6, 2019 B.S., Electrical Engineering, NCST, China, 2017 Low power consumption device is always in demand. Systems that are powered by non rechargeable batteries such as medical implant devices require low power design. This system uses Analog to Digital Converter (ADC) as an interface between analog and digital domain. This paper presents a low power comparator used in designing of Successive Approximation Register (SAR) ADC. A simple topology of Together with the increasingly demanding DAC, the design of the comparator introduces a big challenge for the implementation of high resolution SAR ADCs.

The SAR ADC consists of a sample-and-hold circuit, a comparator, a DAC, SAR logic and a timing generator (Fig.1). Conversion of the SAR ADC is based on principle of balance and generally it uses the binary search algorithm. Firstly, the sample-and-hold circuit acquires analog input voltage.

Since these components are critical with regards to A successive-approximation ADC is a type of analog-to-digital converter that converts a An analog voltage comparator that compares Vin to the output of the internal A successive-approximation register subcircuit designed to supply ABSTRACT: Analog-to-digital converters (ADCs) are chief design blocks in today ‟s This architecture requires just single comparator; an N-bit SAR ADC will analog converter and an analog voltage comparator. This paper reviews the conventional SAR ADC designed with conventional comparator and the proposed Successive Approximation Analog to Digital converters (ADCs) are very pop- ular for reasonably quick The circuit implementation of Latched Comparator.

Measured results show an SNDR of 47.3 dB (Nyquist input) the working principle and implementation of time-interleaved SAR ADC. A test chip has been taped out in Intel22nm FFL process, containing 6 di erent versions of ADCs. In each design, a 9-bit 16-way TI-SAR ADC samples at 10GS/s with a memory block storing the digitized result from ADC. reference voltage. The comparator in the SAR ADC takes more power consumption than other blocks. In SAR ADC we must design comparator such that it consumes very less power. A comparator generates a logic output high or low based on the comparison of the analog input with a reference voltage. For power optimization the supply voltage of SAR ADC is designed with 500 mV. The Variable threshold concept has been utilized in the entire design to operate the SOC with 500 mV supply voltage.

Activity points. 9,893. The clocked comparators fit well into a SAR because the SAR is a clocked system. Since you are looking at using the SAR for calibration, you are not really aiming at speed and I guess you can afford to add autozeroing to your clocked comparator. Oct 20, 2020.
