The first P-doped junction is coupled to the first voltage potential and the second P-doped junction is coupled to the second power supply potential. The third P-doped base junction of the first NPN bipolar transistor is coupled to the third N-doped base junction of the first PNP bipolar transistor. | 10-21-2010 |
20130229736 | ELECTROSTATIC DISCHARGE PROTECTION FOR HIGH VOLTAGE DOMAINS - An electrostatic discharge (ESD) protection device is disclosed. The ESD protection circuit is configured to operate in high voltage domains. The ESD protection device may further include stacked NMOS or PMOS devices. The gates of the MOS devices may be driven by respective inverters. The inverters may be coupled to a voltage divider and may be triggered by respective trigger circuits. Power nodes of the inverters may be connected such that devices in the ESD protection circuit are exposed to voltages that are within their maximum voltage rating. | 09-05-2013 |
20150091056 | SEMICONDUCTOR DEVICE FOR ELECTROSTATIC DISCHARGE PROTECTION - Disclosed is an electrostatic discharge (ESD) protection circuit. The ESD protection circuit may include a silicon controller rectifier (SCR) which may be triggered via at least one of its first trigger gate or second trigger gate. The ESD protection circuit may further include a highly doped region coupled to either the anode or cathode of the SCR, wherein the highly doped region may provide additional carriers to facilitate triggering of the SCR during an ESD event, whereby the SCR may be triggered more quickly. | 04-02-2015 |

20080218920 | METHOD AND APARATUS FOR IMPROVED ELECTROSTATIC DISCHARGE PROTECTION - An apparatus having an inter-domain electrostatic discharge (ESD) protection circuit for protection of an integrated circuit (IC) with multiple power domains. The protection circuit in response to an ESD event provides an ESD protection between different power domains. Specifically, the protection circuit comprises at least one clamp coupled to one power domain, which conducts current during an ESD event to provide extra current in the interface line between the two different power domains. This extra current also in turn increases the voltage over the impedance element on the interface line, thus improving the design margins for the ESD protection and providing a better ESD protection capability for IC products. | 09-11-2008 |
20090195951 | Method and Apparatus for Improved Electrostatic Discharge Protection - An ESD protection circuit having a triggering device, an ESD device and a circuit device coupled between the triggering device and the circuit device such that the circuit device conducts current only in one direction between the ESD device and the triggering device so the ESD device is in an active state for duration longer than time constant of the triggering device. | 08-06-2009 |
20100008002 | High Trigger Current Silicon Controlled Rectifier - An ESD protection circuit including an SCR having at least a PNP transistor and at least a NPN transistor such that said PNP transistor is coupled to an anode and the NPN transistor is coupled to a cathode. The circuit also includes a first resistor coupled between the anode and the base of the pnp transistor and a second resistor coupled between the cathode and the base of the npn transistor. A parasitic distributed bipolar transistor is formed between said first and second transistor to control triggering of the SCR. | 01-14-2010 |

20080285187 | CDM ESD PROTECTION FOR INTEGRATED CIRCUITS - The present invention provides a charged-device model (CDM) electrostatic discharge (ESD) protection circuit for an integrated circuit (IC). The ESD protection circuit comprises a substrate of first conductivity type; a MOS component of second conductivity type formed on a first well on the substrate, and coupled to a pad; an isolating well/region having the second conductivity type being formed between the first well and the substrate to separate the first well and the substrate. Additionally, the circuit comprises an ESD clamp coupled to the isolated well/region. Under normal power operation, the ESD clamp is open. During a CDM ESD event, the CDM charges accumulated in the substrate and the MOS component are removed by the ESD clamp to prevent damage to the IC. | 11-20-2008 |

20150282645 | DUVET COVER SYSTEM AND METHOD OF USING - The present disclosure relates to an improved duvet cover system. The duvet cover system comprises a duvet cover which is washable, reversible, and which may include one or more clips for attaching to and detaching from a duvet or comforter. The one or more clips minimize slippage of the duvet or comforter, prevent uncomfortable bunching, and facilitate keeping the duvet or comforter and duvet cover in a relatively fixed position while duvet cover is opened and closed, while the edges of the duvet cover are at least partially sealed, and while the duvet or comforter is removed from or placed within the cover. | 10-08-2015 |

20150223784 | Liquid Sampler, Kit of Parts, and Method for Assembly - A device for capturing a predetermined volume of a predefined portion (e.g. first void) of a liquid flow, comprises an inlet, an outlet, and a guide with an element displaceable in a first position for capturing the first liquid portion in a reservoir, and in a second position for blocking access to the reservoir, and for passing the liquid to the outlet. The displaceable element moves in transverse direction to the liquid flow, and has lifting means. The element may be substantially flat, or tubular with an elliptical cross section. A kit of parts and a method of assembly are also claimed. | 08-13-2015 |
