Defectivity-immune technique of implementing MIM-based decoupling capacitors
An integrated circuit power supply decoupling circuit includes a capacitor and a protection circuit. The capacitor has a first terminal and a second terminal. The protection circuit includes a first transistor having a first conduction path, and a second transistor having a second conduction path. One terminal of the first conduction path is connected to the first terminal of the capacitor, and another terminal of the first conduction path is connected to a first power supply rail. One terminal of the second conduction path is connected to the second terminal of the capacitor, and another terminal of the second conduction path is connected to a second power supply rail.
