  • Light emitting diode driving circuit and lighting apparatus having the same
    Patent number: 9510414
    Abstract: A light emitting diode (LED) driving circuit includes a flicker elimination unit configured to perform a flicker removal for LED modules and a driving control unit configured to pause a procedure of the flicker removal based on an AC input voltage that is regulated through a Triode for Alternating Current (TRIAC) dimmer, so as to cause a brightness of the LED modules to be dimmed. Therefore, the LED driving circuit selectively adjusts an LED brightness level and removes LED flicker by using a TRIAC dimmer and controls the brightness level of the LED module based on a dimming level.

  • Configurable switch with selectable level shifting
    Patent number: 7145378
    Abstract: A configurable bus switch is described where the bus switches are grouped into combinations as determined by logic inputs. NMOS transistors are the bus switches of choice, and programmable logic inputs select and enable groupings of these switches. Switch enable signals drive the NMOS transistor gates and turn on or off the groups according to the programmable logic inputs. Level shifting and undervoltage protection circuitry is described in preferred embodiments.
