Publication number: 20230035042Abstract: A method for preparing a durably hydrophilic and uniform-pore ultrafiltration membrane is disclosed herein. Chemical reactions between the functional groups and the active bonds of the molecular chains in the membrane materials are initiated perform the grafting of hydrophilic chains on the polymer chains under conventional dissolution conditions of the polymer membrane material (dissolution with synchronized hydrophilization), so as to realize durable hydrophilization of the membrane materials. The resulting hydrophilized polymer solution (a nascent-state membrane) is introduced into a coagulation bath to initiate a crosslinking reaction among the hydrophilic chains. The resulting crosslinking serves to synergistically regulate subsequent phase separation and membrane formation (phase separation under synergistic crosslinking).Type: ApplicationFiled: July 21, 2022Publication date: February 2, 2023Inventors: Chunrui WU, Jingguo SHE, Haifu GAO, Xiaole CHEN, Ziping SONG, Xiaolong LV

Patent number: 7498852Abstract: Circuits, methods, and apparatus for adjusting an NCO output in order to provide a signal that is phase-locked to a reference signal. This is particularly beneficial where the frequencies of the NCO output and reference signal are unrelated. One embodiment provides a circuit that corrects the phase of the NCO output in two steps in order to reduce the chance of metastability. During the first, the output of the NCO is phase shifted to the closest correct portion of a cycle of a clock signal. A second correction is then performed by steering a number of currents under the control of at least some of a number of remainder bits from the NCO. The current steering provides a die area efficient, low-noise phase correction. The decoded remainder bits are latched using a feed forward circuit that prevents the device from entering a locked state.Type: GrantFiled: March 15, 2007Date of Patent: March 3, 2009Assignee: Intersil Americas Inc.Inventors: Sandeep Agarwal, Xiaole Chen

Patent number: 7205798Abstract: Circuits, methods, and apparatus for reducing the phase error in an NCO clock output to reduce the clock jitter. This is particularly beneficial where the frequencies of the NCO output and reference signal are unrelated. One embodiment provides a circuit that corrects the phase of the NCO output in two steps in order to obtain a substantially glitch-free, high-speed operation. During the first step, the output of the NCO is phase shifted to the closest quarter portion of a cycle of a clock signal. A second correction step is then performed by steering a number of currents under the control of at least some of a number of remainder bits from the NCO. The current steering provides a die area efficient, low-noise phase correction. The decoded remainder bits are latched using a feed forward circuit that prevents the device from entering a locked state.Type: GrantFiled: January 28, 2005Date of Patent: April 17, 2007Assignee: Intersil Americas Inc.Inventors: Sandeep Agarwal, Xiaole Chen

Patent number: 6097244Abstract: A continuous-time filter is highly linear even when used with reduced 3-volt power supplies. In each stage of a multi-stage ladder network, resistor networks are attached to each input of a differential op amp. Each resistor network uses fixed resistors in series between the inputs and an intermediate node, and a fixed input resistor between the intermediate node and the op-amp input. The fixed input resistor improves linearity compared with a linear transistor. A transistor connects the internal node to ground, acting as a variable resistor to adjust the equivalent resistance of the resistor network. A control voltage applied to the gate of the transistor is generated by an analog control loop. The control voltage is the voltage input to a voltage-controlled oscillator (VCO) in a phase-locked loop (PLL). The analog PLL control loop adjusts the control voltage and the resistance continuously as the filter operates.Type: GrantFiled: December 17, 1998Date of Patent: August 1, 2000Assignee: Centillium Communications, Inc.Inventor: Xiaole Chen

Patent number: 5923203Abstract: A soft clipper circuit in CMOS technology not only allows the knee to be programmed, but also the slope of the curve after the knee to be programmed. This is accomplished by putting a second transconductance in parallel with the first transconductance, and using a switching circuit to connect the output of the second transconductance to that of the first transconductance when the knee level is reached. This is determined by a comparator which has an input coupled to the second transconductance and controls a control node of the switching circuit.Type: GrantFiled: April 8, 1997Date of Patent: July 13, 1999Assignee: Exar CorporationInventors: Xiaole Chen, Roger Levinson
