    摘要: Through-chip coupling is utilized for signal transport, where an interface is formed between a first coil on a first integrated circuit (IC) chip and a second coil on a second IC chip. The first coil is coupled to an antenna. The second coil is coupled to an amplifier circuit. The second coil is not in direct contact with the first coil. The first coil and the second coil communicatively transmit signals between the antenna and the first amplifier circuit.

    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 ESD protection device includes a first well of a first semiconductor type disposed in a substrate of a second semiconductor type forming a first diode. A second well of the second semiconductor type is formed in the substrate to form a second diode with the first well. A first plurality of doped regions of the first semiconductor type are formed in an upper surface of the first well. A second plurality of doped regions of the second semiconductor type are formed in the upper surface of the first well forming a third diode with the first well. A plurality of STI regions are formed in the upper surface of the first well. Each STI region is disposed between a doped region of the first and second semiconductor types. The third diode provides a current bypass when an ESD voltage spike is received at one of the first or second plurality of doped regions.
