What Does PDN Stand For?

PDN stands for Pull Down Network

PDN, or Pull Down Network, refers to a configuration in integrated circuit design that connects a circuit to ground through transistors when they are in an off state. This technique is crucial for ensuring that the circuit reliably reaches a low logic level, preventing floating inputs that can lead to unpredictable behavior. PDNs enhance signal integrity and improve overall circuit reliability, making them essential in modern electronic systems.
