Cyclic Shear Response of Fine-Sand Tailings Using Cyclic Direct Shear Test

The extraction and processing of mineral and metal ores in the mining industry comes paired with large amounts of mine waste, also known as tailings. This waste consists of various chemicals, acids, and heavy metals which are used during these extraction processes. The tailings are usually stored off in tailings storage facilities (TSF) in a...

DLL Based Single Slope ADC For CMOS Image Sensor Column Readout

This thesis presents a Delay Locked Loop(DLL) based Single Slope ADC. Compared to the convertional Single Slope ADC, the readout speed is increased by 16 times. A DLL is designed with a start-controlled Phase Frequency Detector (PFD), a differential ended Charge Pump (CP) and fully differential Delay Cells (DC). The multi-stage comparator with...
