Optimizing pre-driver control for digital integrated circuits

摘要

Disclosed is a wave shaping apparatus and a method for shaping an input pulse train signal alternating between a low level and a high level to provide a signal delaying a turn on of one output transistor with respect to a turn off of the other output transistor thus decreasing time, when both the transistors would be simultaneously conducting current.

1. A wave shaping apparatus comprising:
a first circuit configured to receive an input pulse train signal alternating between a low level and a high level and to provide a first output pulse train signal comprising a first raise time characterized by a first rate of change between the low level and a first intermediate level and a second rate of change between the first intermediate level and the high level, and a first fall time characterized by a third rate of change between the high level and the low level; and a second circuit configured to receive the input pulse train signal and to provide a second output pulse train signal comprising
a second rise time characterized by a fourth rate of change between the low level and the high level, anda second fall time characterized by a fifth rate of change between the high level and a second intermediate level and a sixth rate of change between the second intermediate level and the low level.
