Conventionally, capacitor-free low dropout regulators (LDO) need a minimum load current to stabilize voltage regulators in normal operation. This minimum load current requirement is a major obstacle to applying capacitor-free LDO regulators in System-on-Chip (SoC) applications. Moreover, most of the.....

Large scale multicast of video and audio materials over IP networks is becoming increasingly popular and common. These services are bandwidth intensive and normally require stringent QoS requirements. Also with millions of heterogeneous participants involved, it is a tough problem to organize the ne.....

A new type of liquid crystal display (LCD) is invented. Common LCDs are transmissive with a front and a back polarizer. For viewing in reflection, a diffuser and a mirror are added to the back of the LCD. The new LCD is a true reflective LCD where there is no rear polarizer. The LCD is simple in.....

A switch capacitor power converter, also known as a charge pump, is a component in the circuit that generates a high voltage using a low input voltage supply that provides power to a load using switches and capacitors. However, existing charge pumps involve too many capacitors and transistors and th.....

This invention presents the fabrication of conductive microstructures embedded in polydimethylsioxane (PDMS) bulk material. The conducting composites are synthesized by mixing nano to micro-sized conductive particles with PDMS gel. Results show that such materials exhibit good electrical conductivit.....
