Power-glitch detection and power-glitch self-testing within a chip is shown. In a chip, a processor has a power terminal, a glitch detector, and a self-testing circuit. The power terminal is configured to receive power. The glitch detector is coupled to the power terminal of the processor for power-glitch detection. The self-testing circuit has a glitch generator and a glitch controller. The glitch controller controls the glitch generator to generate a self-testing glitch signal within the chip to test the glitch detector.

Chip with power-glitch detection and power-glitch self-testing

A wideband antenna includes a grounding terminal, a first radiator disposed on a first plane, a feeding terminal formed on the first radiator, where the feeding terminal is to transmit and receive radio signals via the first radiator, and a second radiator disposed on the first plane, electrically connected to the grounding terminal, and including a part parallel to a side of the first radiator, wherein a minimum gap between the second radiator and the first radiator allows the second radiator and the first radiator to generate a coupling effect therebetween, so as to exchange radio signals between the second radiator and the first radiator.

Wideband antenna

A dipole antenna is disclosed. The dipole antenna includes a feed-in terminal, a balun, a first radiator and a second radiator. The feed-in terminal is used for feeding in a radio-frequency signal. The balun is electrically connected to the feed-in terminal for driving out a return current of the dipole antenna to balance a feed-in impedance of the dipole antenna. The first radiator is electrically connected to the feed-in terminal and the balun for radiating the radio-frequency signal in a first frequency band. The second radiator is electrically connected to the first radiator, the feed-in terminal and the balun for radiating the radio-frequency signal in a second frequency band.
