    摘要: The present disclosure relates to an on-chip electrostatic discharge (ESD) protection circuit that may be reused for a variety of integrated circuit (IC) applications. Both inductor-capacitor (LC) parallel resonator and shunt inductor (connected to ground) are used as ESD protection circuits and also as a part of an impedance matching network for a given IC application. The ESD LC resonator can be designed with a variety of band pass filter (BPF) topologies. On-chip ESD protection circuit allows for co-optimization ESD and BPF performance simultaneously, a fully on-chip ESD solution for integrated passive device (IPD) processes, eliminates a need for active ESD device protection, additional processes to support off-chip ESD protection, reduces power consumption, and creates a reusable BPF topology.

    摘要: A built-in self-test circuit for testing a voltage controlled oscillator comprises a voltage controlled oscillator, a buffer having an input coupled to an output of the voltage controlled oscillator and a radio frequency peak detector coupled to the output of the buffer. The radio frequency peak detector is configured to receive an ac signal from the voltage controlled oscillator and generate a dc value proportional to the ac signal at an output of the radio frequency peak detector. Furthermore, the output of the radio frequency peak detector generates a dc value proportional to an amplitude of the ac signal from the voltage controlled oscillator when the voltage controlled oscillator functions correctly. On the other hand, the output of the radio frequency peak detector is at zero volts when the voltage controlled oscillator fails to generate an ac signal.

    摘要: An auxiliary lighting device for vehicle lamps which is a refractive body is revealed. One end of the refractive body is a light emitting surface and the other end is a tapered curved surface. Moreover, curved light-gathering ridge lines and an emitter receiving slot for mounting light emitting diode (LED) are disposed on one end of the refractive body having the curved surface. Thereby linear light emitted from the LED is refracted by the emitter receiving slot into a plurality of radial lines. Then the radial lines are gathered by the curved surface to be emitted from the light emitting surface. The light refracted to the surface of the refractive body is guided by the light-gathering ridge lines to project toward the end of the refractive body with the light emitting surface. Therefore, intensity of the light from vehicles lamps is increased significantly to provide excellent illumination and warning signals.
