Power supply di/dt measurement using on-chip di/dt detector circuit
説明
This paper demonstrates an on-chip di/dt detector circuit. The di/dt detector circuit consists of a spiral inductor under the power supply line which induces a di/dt proportional voltage, and an amplifier which amplifies and outputs the value. The measurement results show that the di/dt detector output and the voltage difference between a resistor have good agreement. The di/dt detector also measures the de-coupling capacitor effects for the di/dt reduction.
