  • Mark antenna and electronic device
    Patent number: 8698679
    Abstract: The present invention discloses a mark antenna used for receiving and transmitting a wireless signal. The mark antenna comprises a ground point, a feed point and a radiation part connecting to the ground point and the feed point, and particularly the radiation part is an identification mark, such that the appearance of the radiation part can provide identification information. With the light, thin, short and compact design concept, the mark antenna can be exposed to prevent the antenna from being compressed due to the small disposed area and overcome the difficulty of designing the antenna or a poor communication quality caused by the low performance of the antenna. In the present invention, the antenna is designed as a logo directly, such that the antenna can achieve the functions of identifying the appearance as well as transmitting and receiving the wireless signals.

  • SIGE BASED GATE DRIVEN PMOS TRIGGER CIRCUIT
    Publication number: 20130342941
    Abstract: Some embodiments of the present disclosure relate to a low-power, area efficient ESD protection device that provides ESD protection to an ESD susceptible circuit. The ESD protection device has a trigger circuit with a resistor. The resistor has a first terminal connected to the first external pin and a second terminal connected directly to a gate of a SiGe based PMOS shunt transistor. The trigger circuit generates a trigger signal that drives the gate of the PMOS device to shunt power away from the ESD susceptible circuit when an ESD event is present. The SiGe based PMOS shunt transistor has a lower gate leakage than a conventional NMOS shunt transistors, thereby providing for an ESD circuit with a low leakage current at small gate lengths.
