介绍了一种用于供电线路的片上di/dt检测电路。di/dt检测器由电源下的螺旋电感和容噪放大器组成。前者通过互感耦合产生di/dt比例电压，后者将感应电压线性放大。仿真结果表明，该检测器测量di/dt的精度为1.52/spl倍/10/sup 7/ A/s。对di/dt积分得到电流波形，在平均电流为50 mA时，精度为0.72 mA。
This paper describes an on-chip di/dt detector circuit for power supply lines. The di/dt detector consists of a spiral inductor under the power supply line and a noise-tolerant amplifier. The former induces a di/dt proportional voltage by means of mutual inductive coupling, and the latter amplifies the induced voltage linearly. Simulation results show that the detector can measure the di/dt with an accuracy of 1.52/spl times/10/sup 7/ A/s. The current waveform can be obtained by integrating the di/dt, and the result shows 0.72 mA accuracy at an average current of 50 mA.
