Patent number: 11962313Abstract: An oscillator circuit is provided that adapts to voltage supply variations. The circuit first and second delays lines connected inputs of an edge detector, one delay line supplied by a reference voltage and the other with a drooping supply voltage. The edge detector generates an output clock based on a relationship between the inputs. The output clock applied to the signal inputs of the first and second delay lines. The output clock has a voltage dependent frequency performance curve with a slope dependent at least on the second delay line delay and a delay of the edge detector. At least one of the first delay line, the second delay line, and the edge detector delay are adjusted to change the slope of the performance curve.Type: GrantFiled: March 29, 2019Date of Patent: April 16, 2024Assignees: Advanced Micro Devices, Inc., ATI Technologies ULCInventors: Stephen Victor Kosonocky, Mikhail Rodionov, Joyce Cheuk Wai Wong

Publication number: 20240106438Abstract: An integrated circuit includes a power supply monitor, a clock generator, and a divider. The power supply monitor is operable to provide a trigger signal in response to a power supply voltage dropping below a threshold voltage. The clock generator is operable to provide a first clock signal having a frequency dependent on a value of a frequency control word, and to change the frequency of the first clock signal over time using a native slope in response to a change in the frequency control word. The divider is responsive to an assertion of the trigger signal to divide a frequency of the first clock signal by a divide value to provide a second clock signal.Type: ApplicationFiled: November 30, 2023Publication date: March 28, 2024Applicants: Advanced Micro Devices, Inc., ATI Technologies ULCInventors: Kaushik Mazumdar, Ashish Jain, Joyce Cheuk Wai Wong, Mikhail Rodionov

Patent number: 11936382Abstract: An output clock frequency of an adaptive oscillator circuit changes in response to noise on an integrated circuit power supply line. The circuit features two identical delay lines which are separately connected to a regulated supply and a droopy supply. In response to noise on the droopy supply, the delay lines cause a change in the output clock frequency. The adaptive oscillator circuit slows down the output clock frequency when the droopy supply droops or falls below the regulated supply. The adaptive oscillator circuit clamps the output clock frequency at a level determined by the regulated supply when the droopy supply overshoots or swings above the regulated supply.Type: GrantFiled: June 27, 2019Date of Patent: March 19, 2024Assignees: Advanced Micro Devices, Inc., ATI TECHNOLOGIES ULCInventors: Joyce Cheuk Wai Wong, Dragoljub Ignjatovic, Mikhail Rodionov, Ljubisa Bajic, Stephen V.

Publication number: 20220408625Abstract: A tillage implement for variable tillage has a linkage mechanism disposed longitudinally between two gangs of annular harrow tools, the gangs each having a toolbar that is rotationally mounted on a frame of the implement. The linkage mechanism has a plurality of pivotally connected linkage arms, the toolbars each pivotally connected to at least one of the linkage arms. Operation of the linkage mechanism simultaneously rotates one toolbar about a first vertical rotation axis and the other toolbar about a second vertical rotation axis in an opposite rotational direction as the first toolbar. The implement has at least one wheel mounted on the frame longitudinally forward of both of the gangs or longitudinally rearward of both of the gangs. The tillage implement provides variable tillage while having a shorter frame to facilitate folding wing sections of the frame in a more compact manner for transportation while remaining assembled.Type: ApplicationFiled: November 27, 2020Publication date: December 29, 2022Inventors: Geof J.

Patent number: 9455722Abstract: In a method and apparatus for using a clock generating circuit to minimize settling time after dynamic power supply voltage ramping, a clock signal may be generated using a clock generating circuit having, among other things, open feedback loop switch logic and a dynamic fast lock control signal generator. Whereupon, when in operation, the open feedback loop switch logic is responsive to a controlled change in power supply voltage condition such that a feedback loop of the clock generating circuit is opened during power supply voltage ramping (e.g., during transitions to or from battery conservation modes). In response to opening the feedback loop, the dynamic fast lock control signal generator selectively applies a stabilizing control signal to a variable clock signal generator (e.g., a voltage controlled oscillator) such that the generated clock signal can quickly lock onto the proper target frequency.Type: GrantFiled: November 30, 2005Date of Patent: September 27, 2016Assignee: ATI Technologies ULCInventors: Shirley Lam, Nancy Chan, Mikhail Rodionov, Ramesh Senthinathan
