在电子工程中，接地反弹（英语：Ground bounce）是指与晶体管切换状态时，阈值电压呈现比当时接地环路更低电压的现象。接地反弹会造成逻辑门工作不稳定。

In electronic engineering, ground bounce is a phenomenon associated with transistor switching where the gate voltage can appear to be less than the local ground potential, causing the unstable operation of a logic gate.
