1. 1. Temperature Compensation in CMOS Ring Oscillator

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Xiaohua Wei; Dingyufei Zhang; [2022]
   Keywords : Current Starved Ring Oscillator CSRO ; Temperature compensation; Supply voltage compensation; Stable frequency; Digital controlling; Phase Frequency Detector PFD ; Dynamic comparator; Bidirectional counter; Charge pump CP ; Frequency divider; Power consumption; AMS 0.35 um; EDA tool Cadence;

   Abstract : A digital system is often required to operate under a specific frequency. A ring oscillator can be helpful in this circumstance because it can generate a signal with a specific frequency. However, a ring oscillator is also sensitive to the environment temperature. READ MORE

3. 2. A design of a 100 MS/s, 8-bit Pipelined ADC in CMOS

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Shen Zhang; [2021]
   Keywords : Technology and Engineering;

   Abstract : The thesis focuses on designing and simulating an 8-bit high-speed fully differential pipelined Analog to Digital Converter (ADC) in the 65nm Complementary Metal-Oxide-Semiconductor (CMOS) technology by using the software Cadence Virtuoso. The aim is to increase the operation speed of the ADC for communication systems without reducing the performance, in the meantime, the low power consumption and the low complexity should also be required when considering future implementation.

4. 3. Design of a 12-bit 200-MSps SAR Analog-to-Digital converter

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Luca Ricci; [2020]
   Keywords : ;

   Abstract : The Successive Approximation (SAR) Analog-to-Digital converter is one of the most energy-efficient A/D converter. In this thesis, the development of a SAR ADC in a 28-nm CMOS technology based on charge redistribution is presented. READ MORE

5. 4. Implementation of a 200 MSps 12-bit SAR ADC

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Victor Gylling; Robert Olsson; [2015]
   Keywords : SAR; ADC; MCS; converter; circuit design; capacitor; Technology and Engineering;

   Abstract : Analog-to-digital converters (ADCs) with high conversion frequency, often based on pipelined architectures, are used for measuring instruments, wireless communication and video applications. Successive approximation register (SAR) converters offer a compact and power efficient alternative but the conversion speed is typically designed for lower frequencies. READ MORE
