Patent number: 9994595Abstract: Described herein is the fusion of two families of unique carbon-containing molecules that readily disregard the tendency of carbon to form four chemical bonds, namely N-heterocyclic carbenes (NHCs) and carborane anions. Deprotonation of an anionic imidazolium salt with lithium diisopropylamide at room temperature leads to a mixture of lithium complexes of C-2 and C-5 dianionic NHC constitutional isomers as well as a trianionic (C-2, C-5) adduct. Judicious choice of the base and reaction conditions allows for the selective formation of all three stable polyanionic carbenes. In solution, the so-called abnormal C-5 NHC lithium complex slowly isomerizes to the normal C-2 NHC, and the process can be proton catalyzed by the addition of the anionic imidazolium salt. These results indicate that the combination of two unusual forms of carbon atoms can lead to unexpected chemical behavior, and that this strategy paves the way for the development of a broad new generation of NHC ligands for catalysis.Type: GrantFiled: March 16, 2015Date of Patent: June 12, 2018Assignee: The Regents of the University of CaliforniaInventors: Vincent Lavallo, Ahmad El Hellani, Allen Chan

Patent number: 9246715Abstract: A pre-emphasis circuitry that includes (1) a pre-emphasis voltage variation compensation (PVVC) engine having a transition detection circuit and (2) a compensation driver coupled to the PVVC engine is described. In one embodiment, the compensation driver reduces data dependent voltage variations in pre-emphasis provided by the pre-emphasis circuitry. In one embodiment, in response to a predetermined data pattern detected by the PVVC engine, the compensation driver provides an additional boost to performance critical capacitive nodes of the pre-emphasis circuitry. The additional boost causes the performance critical capacitive nodes to charge or discharge more rapidly. In one embodiment, the PVVC engine further includes a digital finite impulse response (FIR) filter coupled to the transition detection circuit.Type: GrantFiled: April 29, 2009Date of Patent: January 26, 2016Assignee: Altera CorporationInventors: Allen Chan, Wilson Wong, Tim Tri Hoang

Patent number: 9215115Abstract: An embodiment of the present invention implements a linear feedback shift register (LFSR) as a counting device for an integrator of a DFE circuit. In embodiments of the present invention, the particular count sequence need not be known, instead only boundary values need be known. For example, for a LFSR having a predetermined count sequence, a digital integrator controller need not know every value of the count sequence. Instead, the digital integrator controller detects predetermined boundary values such as a minimum or maximum count.Type: GrantFiled: December 3, 2012Date of Patent: December 15, 2015Assignee: Altera CorporationInventor: Allen Chan

Patent number: 8831140Abstract: Automatic rate negotiation logic for a high speed serial interface in a programmable logic device determines whether multiple occurrences of a single-bit transition (i.e., a data transition from “0” to “1” to “0” or from “1” to “0” to “1”) occur within a predetermined time interval on a data channel of a high-speed serial interface. The interval preferably is selected such that multiple occurrences of a single-bit transition mean that the data channel is operating in full-rate mode. The rate negotiation logic may share a phase detector with clock data recovery circuitry in the interface. The phase detector may be a bang-bang phase detector specially adapted to detect single-bit transitions.Type: GrantFiled: March 16, 2007Date of Patent: September 9, 2014Assignee: Altera CorporationInventors: Allen Chan, Wilson Wong, Sergey Shumarayev

Patent number: 8767801Abstract: The ability of clock and data recovery (“CDR”) circuitry on an integrated circuit (“IC”) to handle jitter in a serial data input signal can be tested by using transmitter circuitry on the IC to produce a serial data output signal whose time base has been subjected to modulation. Loop-back circuitry on the IC may be used to apply the serial data output signal to the CDR circuitry as the serial data input signal of the CDR circuitry. Modulation circuitry on the IC may be used to cause the above modulation of the time base of the serial data output signal.Type: GrantFiled: March 23, 2010Date of Patent: July 1, 2014Assignee: Altera CorporationInventors: Allen Chan, Wilson Wong

Patent number: 8699648Abstract: One embodiment relates to a method of offset cancellation for a receiver in an integrated circuit. The receiver is set to a phase-detector offset-cancellation mode so as to determine offset cancellation settings for the phase detector. The offset cancellation settings are applied to the phase detector. The receiver is then set to a receiver-driver offset-cancellation mode so as to determine an offset cancellation setting for the receiver driver. This offset cancellation setting is applied to the receiver driver. Another embodiment relates to an integrated circuit configured to perform receiver offset cancellation. The integrated circuit including a receiver driver configured to receive a differential input signal, a phase detector including a plurality of latches, a calibration controller, a voltage source, and first and second pairs of switches. Other embodiments, aspects, and features are also disclosed.Type: GrantFiled: February 22, 2013Date of Patent: April 15, 2014Assignee: Altera CorporationInventors: Allen Chan, Wilson Wong, Sergey Shumarayev

Patent number: 8669828Abstract: Integrated circuits with decoupling capacitor circuitry are provided. Decoupling capacitor circuitry may include multiple arrays of decoupling capacitors. Each decoupling capacitor array may have a corresponding decoupling capacitor monitoring circuit that is associated with that decoupling capacitor array. Each decoupling capacitor monitoring circuit may include a resistor and switching circuitry. Each decoupling capacitor monitoring circuit may be coupled to a comparator and control circuitry. During testing, the control circuitry may configure each decoupling capacitor array for leakage current testing one at a time. If a decoupling capacitor array is determined to exhibit excessive leakage currents, that decoupling capacitor array will be marked as defective and will be disabled from use. If the decoupling capacitor array is determined to exhibit tolerable leakage currents, that decoupling capacitor array will be enable for use to help reduce power supply noise.Type: GrantFiled: October 21, 2010Date of Patent: March 11, 2014Assignee: Altera CorporationInventors: Wilson Wong, Allen Chan, Sergey Shumarayev
