Patent number: 9347836Abstract: A system and method for measuring integrated circuit (IC) temperature. An integrated circuit (IC) includes a thermal sensor and data processing circuitry. The thermal sensor utilizes switched currents provided to a reference diode and a thermal diode. The ratios of the currents provided to each of these diodes may be chosen to provide a given delta value between the resulting sampled diode voltages. At a later time, a different ratio of currents may be provided to each of these diodes to provide a second given delta value between the resulting sampled diode voltages. A differential amplifier within the data processing circuitry may receive the analog sampled voltages and determine the delta values. Other components within the data processing circuitry may at least digitize and store one or both of the delta values. A difference between the digitized delta values may calculated and used to determine an IC temperature digitized code.Type: GrantFiled: November 15, 2011Date of Patent: May 24, 2016Assignee: ATI Technologies ULCInventors: Grigori Temkine, Filipp Chekmazov, Paul Edelshteyn, Oleg Drapkin, Kristina Au

Patent number: 8570067Abstract: An integrated circuit is capable of controlling a communication signal by using power ramp controlled communication buffer logic to generate an outgoing communication signal based on a detected voltage on a voltage source. The voltage source is necessary to supply power for power ramp controlled communication buffer logic. The voltage on the voltage source may be detected using power ramp sensor logic. The outgoing communication signal is based on a core logic output signal if the detected voltage is greater than or equal to a predetermined voltage level. If, the detected voltage is less than the predetermined voltage level, the outgoing communication signal is predetermined to be one of: a tristate outgoing communication signal, a logic one outgoing communication signal and a logic zero outgoing communication signal. Power ramp controlled communication buffer logic may also generate a core logic input signal based on an incoming communication signal in response to the detected voltage.Type: GrantFiled: May 15, 2007Date of Patent: October 29, 2013Assignees: ATI Technologies ULC, Advanced Micro Devices, Inc.Inventors: Oleg Drapkin, Grigori Temkine, Marcus Ng, Kevin Yikai Liang, Arvind Bomdica, Siji Menokki Kandiyil, Ming So, Samu Suryanarayana

Publication number: 20130144549Abstract: A system and method for calibrating integrated circuit (IC) temperature measurement circuits. An integrated circuit (IC) includes a thermal sensor and data processing circuitry. The IC may have a temperature measurement mode of operation and a calibration mode of operation. During the calibration mode, one or more stable reference voltages, rather than sensed voltages from a thermal sensor, are selected as input voltages to the data processing circuitry. Electronic components within the data processing circuitry receive the stable reference voltages and generate a temperature digital code. The generated temperature digital code may be compared to an expected temperature digital code based on theoretical ideal gains for each of the components within the data processing circuitry. The comparison leads to an updated value for a scaling factor to be stored and used in subsequent temperature measurements.Type: ApplicationFiled: December 1, 2011Publication date: June 6, 2013Inventors: Grigori Temkine, Filipp Chekmazov, Paul Edelshteyn, Oleg Drapkin, Kristina Au
