Injection locked ring oscillator design for application in Direct Time of Flight LIDAR
 Fránek, Jakub ; Háze, Jiří (oponent) ; Kledrowetz, Vilém (vedoucí práce)
The diploma thesis provides an introduction to Direct Time of Flight LIDAR systems and Time to Digital Converters used in these systems. It discusses the problem of clock distribution in LIDAR Time to Digital Converter arrays, and examines one of the possible solutions to this problem based on injection locked oscillators. The injection locking phenomenon is thoroughly mathematically described and a Matlab model of an injection locked ring oscillator is presented, confirming the analytic predictions. In ONK65 processing technology, an injection locked ring oscillator biased by a delay locked loop meant specifically for application in Time to Digital Converters for LIDAR systems has been designed. The designed oscillator has been verified by computer simulations taking process, voltage and temperature variations into account and offers specified time resolution of 50 picosecond as well as two times less clock jitter than an equivalent free-running oscillator in the given processing technology.
