Patent number: 10920252Abstract: It has been found that esterification of a hydroxy-fatty acid by a lipase can be coupled with oleate hydratase (OHase) generation of that hydroxy-FA from an unsaturated FA with a cis C9-C10 double bond, e.g. oleic acid, in a single aqueous buffered reaction medium at low temperature, e.g. 30° C.

Patent number: 10892935Abstract: A wideband, linear, direct-digital RF modulator (DDRM) for a digitally-intensive transmitter (DTX) includes an interpolation filter and an in-phase/quadrature (I/Q)-interleaving RF digital-to-analog converter (RF-DAC). The interpolation filter suppresses sampling replicas in the DDRM's output RF spectrum. I/Q interleaving performed by the interleaving RF-DAC avoids problems associated with using two separate I- and Q-path RF-DACs. Each unit cell of the interleaving RF-DAC is capable of producing four unique non-overlapping waveforms covering all four quadrants of the I/Q signal plane. In one embodiment of the invention, the interleaving RF-DAC includes three parallel-connected RF-DACs operating in accordance with a multi-phase set of LO clocks to both cancel 3rd-order and 5th-order LO harmonics generated by the RF-DAC unit cells' interleaving logic and prevent 3rd-order intermodulation from occurring in the DTX's final stage RF power amplifier.Type: GrantFiled: May 30, 2018Date of Patent: January 12, 2021Assignee: Technische Universiteit DelftInventors: Mohammed Reza Mehrpoo, Leonardus Cornelis Nicolaas de Vreede, Seyed Morteza Alavi

Patent number: 10892548Abstract: A photoconductive antenna has an array of antenna electrodes on or in a photoconductive substrate. The photoconductive substrate is irradiated with light from a pulsed laser via micro-lenses above respective gaps between antenna electrodes. This makes the photoconductive substrate temporarily conductive, causing pulsed electric antenna currents that can be used for transmission of electromagnetic radiation in the Terahertz range. The bias circuit of the antenna is configured to determine voltages applied to the antenna electrodes by capacitive voltage division over a series of successive capacitors, each capacitor being formed by the antenna electrodes of a respective pair of successive ones of the antenna electrodes in the array as plates of the capacitor adjacent to a respective one of the gaps.Type: GrantFiled: August 4, 2016Date of Patent: January 12, 2021Assignee: TECHNISCHE UNIVERSITEIT DELFTInventors: Andrea Neto, Alessandro Garufo, Giorgio Carluccio, Nuria Llombart Juan

Patent number: 10872956Abstract: Quantum dot circuit and a method of characterizing such a circuit Voltages that enable control of electron occupation in a series of quantum dots are determined by a method of measuring effects of gate electrode voltages on a quantum dot circuit. The quantum dot circuit comprises a channel (10), first gate electrodes (14a-14e) that extend over locations along the edge of the channel to create potentials barriers defining the potentials well therebetween, as well as second gate electrodes (16a-16d) adjacent to potential wells, for controlling depths of the successive electrical potential wells between the potential barriers. First, channel currents are measured in a pre-scan of bias voltages of the first gates for controlling the potential barriers. The result is used to set their bias levels in, a scan over a two-dimensional range of combinations of bias voltages on the second gates for controlling the depths.Type: GrantFiled: March 6, 2017Date of Patent: December 22, 2020Assignees: Nederlandse Organisatie voor toegepast-natuurwetenschappelijk onderzoek TNO, Technische Universiteit DelftInventors: Pieter Thijs Eendebak, Timothy Alexander Baart, Lieven Mark Koenraad Vandersypen

Patent number: 10819379Abstract: A digitally-controlled power amplifier (DPA) includes a radio frequency digital-to-analog converter (RF-DAC) constructed from nonlinearly weighted PA segments, a multiphase RF drive signal generator that drives the PA segments, and overdrive voltage control circuitry. The nonlinear weighting of the PA segments intrinsically compensates for amplitude-code-word dependent amplitude distortion (ACW-AM distortion) involved in the operation of the RF-DAC and the multiphase RF drive signal generator facilitates ACW-dependent phase distortion (ACW-PM distortion) reduction, thus obviating the need for complicated and efficiency-degrading digital predistortion. The overdrive voltage control circuitry is used to fine tune the RF output of the DPA and compensate for other non-idealities and external influences such as process, voltage, temperature (PVT), frequency and/or load impedance variations.Type: GrantFiled: April 15, 2020Date of Patent: October 27, 2020Assignee: Technische Universiteit DelftInventors: Mohsen Hashemi, Leonardus Cornelis Nicolaas de Vreede

Publication number: 20200265334Abstract: Embodiments of the present disclosure provide improved layout designs for quantum circuit assemblies employing qubits, e.g. superconducting qubits. One proposed design involves increasing a capacitance between a first qubit and a coupling component that couples the first qubit to a second qubit. Another design involves rounding of one or more corners at the end portions of coupling components. Yet another design involves varying the distance between two electrically conductive elements of a given superconducting qubit device which are connected to one another via one or more non-linear inductive elements.
