Abstract
A method and system that may include a pair of amplifier transistors and an output coupled to a load device. The precharge buffer may be controlled by an activation signal. The precharge buffer may also include a pair of level shifters. Each level shifter may be provided in association with a respective one of the transistors, and each may provide a respective level shift to an input signal at a common signal source based on a reference voltage. Outputs of the level shifters may be coupled to the respective transistors. The precharge buffer may also include a bypass signal path extending from the common signal source to the load device. A signal path may be controlled by another activation signal, and the precharge buffer and the bypass signal may be enabled during mutually exclusive states of the activation signal.
