Modeling and Measurement of Ground Bounce Induced by High-Speed Output Buffer With On-Chip Low-Dropout (LDO) Regulator

This study proposes a model of ground bounce induced by a high-speed output buffer with on-chip low-dropout (LDO) regulator. When the output buffer operates with a high-speed clock, high output impedance of the pass transistor and low impedance of the on-chip decoupling capacitor at load enable the ground bounce calculation by only using the self-impedance of the off-chip ground network and switch...
