Design and measurement of on-chip di/dt detector circuit for power supply line

This paper demonstrates design and measurement of an on-chip di/dt detector circuit for power supply line. 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 di/dt detector is mounted on Cu board, and the measurement results show that the di/dt detector output and the voltage difference between a resistor have good agreement.
