High performance zero-crossing based pipelined analog-to-digital converters
As CMOS processes continue to scale to smaller dimensions, the increased fT of the devices and smaller parasitic capacitance allow for more power efficient and faster digital circuits to be made. But at the same time, output impedance of transistors has gone down, as have the power supply voltages, and leakage currents have increased. These changes in the technology have made analog design more...

متن کاملA High Performance Zero - Crossing Based Pipelined Analog - to - Digital Converter
In this thesis, I describe a zero-crossing based pipelined ADC. Unlike traditional pipelined ADCs, this work does not use any op-amps in the signal path. The use of zero-crossing based circuits made it possible to achieve a much better figure of merit. The ADC is design to operate at 200MS/s with a resolution of 12 bits. The simulated results suggest that the target performance is achievable wi...
متن کاملA Zero - Crossing Based Pipelined Analog - to - Digital Converter with Supply Voltage
A zero-crossing based pipelined analog-to-digital converter (ADC) has been designed and is fabricated in a 65nm CMOS process. The highly digital implementation characteristic of the zero-crossing detection technique enables energy efficient operation and voltage scaling. Supply voltage scaling based on the required sampling frequency and resolution provides high energy efficiency over a wide ra...
متن کاملReconfigurable Ultrasonic Testing System Development Using Programmable Analog Front-End and Reconfigurable System-on-Chip Hardware
Ultrasonic testing systems have been extensively used in medical imaging and non-destructive testing applications. Generally, these systems aim at a particular application or target material. To make these systems portable and more adaptable to the test environments, this study presents a reconfigurable ultrasonic testing system (RUTS), which possesses dynamic reconfiguration capabilities. RUTS...
