New bang-bang phase detectors for high-speed serial links

Bang-bang phase detector studies were carried out in this thesis. Based on the comparison of linear and non-linear phase detectors, a hybrid phase detector was proposed. It possesses the characteristics of two-XOR phase detectors and improved bang-bang phase detectors. PLLs with the proposed hybrid phase detector possess low timing jitter in lock states and a fast locking process. The effectiveness of the proposed hybrid phase detector was quantified by comparing the performance of three PLLs with identical loop components but different phase detectors. A new bang-bang phase detector with regenerative DFFs was also proposed. The regenerative bang-bang phase detector ensures a fast acquisition of incoming clocks. The effectiveness of the regenerative phase detector was assessed in a 2GHz PLL. A 1X bang-bang phase detector was proposed also. Compared to a 2X bang-bang phase detector, PLLs with a 1X bang-bang phase detector offer faster locking. A DFF frequency detector and a charge-pump frequency detector were also proposed. Both effectively detect the frequency difference.

Frequency Tracking Of A Prototype Elliptical RF Cavity

Remarkable development with the use of microwave cavity has occurred during the last two to three decades, particularly in portable correspondence, TV transmission, modern/local applications, satellite correspondence, telemetry, RADAR/navigational guides, and so forth. This quick improvement inside the microwave which of computerized advances has synergized, bringing about further quickened rate. The paper reports primarily on the frequency tracking system probably be coupled with radio frequency (RF) cavity. For the creating and testing of the tracking system, we have used phase detectors and loop filters throughout. The quality of the tracking system and thus the underlying scanning results were seen to help the realistic tests.

Electroluminescence and Electron Avalanching in Two-Phase Detectors

Electroluminescence and electron avalanching are the physical effects used in two-phase argon and xenon detectors for dark matter searches and neutrino detection, to amplify the primary ionization signal directly in cryogenic noble-gas media. We review the concepts of such light and charge signal amplification, including a combination thereof, both in the gas and in the liquid phase. Puzzling aspects of the physics of electroluminescence and electron avalanching in two-phase detectors are explained, and detection techniques based on these effects are described.
