Patent number: 11711085Abstract: Embodiments of the present disclosure provide systems and methods for realizing phase synchronization updates based on an input system reference signal SYSREF without the need to synchronously distribute the SYSREF signal on a high-speed domain. In particular, phase synchronization mechanisms of the present disclosure are based on keeping a first phase accumulator in the device clock domain and using a second phase accumulator in the final digital clock domain to asynchronously transmit phase updates to the final digital clock domain. Arrival of a new SYSREF pulse may be detected based on the counter value of the first phase accumulator, which value is asynchronously transferred and scaled to the second phase accumulator downstream. In this manner, even though the SYSREF signal itself is not synchronously transferred to the second phase accumulator, the phase updates from the SYSREF signal may be transferred downstream so that the final phase may be generated deterministically.Type: GrantFiled: May 2, 2022Date of Patent: July 25, 2023Assignee: Analog Devices International Unlimited CompanyInventors: Alexander Leonard, Lu Wu, Christopher Mayer, Gord Allan

Patent number: 11670735Abstract: An electrical power converter can include a plurality of layers disposed on a substrate. An emitter, including a first semiconductor junction that is formed at an interface between a first pair of adjacent layers, can produce light in response to a first electrical signal.
