Patent number: 10847112Abstract: A VCOM generator circuit generates a VCOM signal for an electronic display. The VCOM circuit includes an operational amplifier having reduced supply rails. In an implementation, the VCOM circuit has at least three supply rails, AVDD, ground or GND, and VP or VN, or both. VP is less than AVDD and greater than VN. VN is higher than ground and below VP. The VCOM circuit with reduced voltage supply rails for VP and VN reduces power consumption of the VCOM op amps. By reducing power consumption, this also reduces the surface temperature of the integrated circuit.Type: GrantFiled: January 26, 2017Date of Patent: November 24, 2020Assignee: IML InternationalInventors: Alberto Giovanni Viviani, Dimitry Goder, JunGi Lee, ChinFa Kao, Chun Lu

Patent number: 10749432Abstract: A voltage converter includes a low dropout regulator voltage converter circuit. The voltage converter generates three voltages (e.g., 1.2 volts, 2.5 volts, and 1.8 volts) for an electronic system, which can be a smartphone or electronic tablet or other device. An implementation has at least one charge pump voltage converter circuit. The low dropout regulator voltage converter circuit provides an output voltage based on its input voltages and can operate with a very small input-to-output differential voltage. Compared to using a Buck converter, a low dropout regulator does not have an external inductor, which saves space. An implementation of the voltage converter can also include at least one charge pump voltage converter circuit to generate a voltage of the voltage converter.Type: GrantFiled: July 29, 2016Date of Patent: August 18, 2020Assignee: IML InternationalInventors: Alberto Giovanni Viviani, Dimitry Goder

Light-emitting diode lighting device having multiple driving stages and line/load regulation control
Patent number: 9313839Abstract: An LED lighting device includes multiple luminescent devices driven by a rectified AC voltage. The multiple luminescent devices are turned on flexibly in a multi-stage driving scheme using multiple current controllers. The current settings of the two driving stages with the highest current level and the second highest current level are adjusted according to the variation in the rectified AC voltage VAC or according to the variation in the duty cycle of the luminance device due to the variation in the rectified AC voltage. The present invention can improve the line/load regulation of the LED lighting device when the rectified AC voltage somehow fluctuates between its upper bound and lower bound.Type: GrantFiled: March 18, 2015Date of Patent: April 12, 2016Assignee: IML InternationalInventors: Alberto Giovanni Viviani, Dimitry Goder, Chun Lu, Kai-Yun Cheng -

Publication number: 20120187768Abstract: DC to DC converters are connected in parallel to a DC buss that is input to a DC to AC inverter module. Each of the DC to DC converters receives input from one or more DC electrical sources. The inverter module typically comprises a DC to AC power stage that is connectable to an AC buss, and a filter connected between the DC buss and the DC to AC power stage. The filter may comprise one or more capacitors, wherein the capacitors may be chosen based upon the voltage of the DC buss. While the DC buss may have a voltage ripple associated therewith, the DC electrical sources are protected from the DC voltage ripple by their respective converter modules.Type: ApplicationFiled: January 25, 2012Publication date: July 26, 2012Inventors: Dimitry Goder, Eugene Krzywinski, James Allen, Troy Speers
