    摘要: A device includes a control circuit, a scope circuit, and a time-to-current converter. The control circuit is configured to receive a voltage signal from a voltage-controlled oscillator, delay the voltage signal for a delay time to generate a first control signal, and to generate a second control signal according to the first control signal and the voltage signal. The scope circuit is configured to generate a first current signal in response to the second control signal and the voltage signal. The time-to-current converter is configured generate a second current signal according to the first control signal, the voltage signal, a first switch signal, and a test control signal.

    摘要: In some embodiments, an integrated circuit device includes a semiconductor substrate. An active area is disposed in the semiconductor substrate. A first guard ring is disposed in the semiconductor substrate and entirely surrounds the active area. The first guard ring has a first conductivity type. A via penetrates through the semiconductor substrate and is spaced apart from the active area such that the via is disposed outside of the first guard ring. A second guard ring is disposed in the semiconductor substrate and entirely surrounds the via and the first guard ring. The second guard ring has the first conductivity type and is disjoint from the first guard ring.

    摘要: A device is disclosed that includes a control circuit and a scope circuit. The control circuit is configured to delay a voltage signal to generate a first control signal. The scope circuit is configured to be operated in one of a first mode and a second mode according to the first control signal. In the first mode, the scope circuit is configured to generate a first current signal indicating amplitudes of the voltage signal, and in the second mode, the scope circuit is configured to stop generating the first current signal.
