Circuit for address transition detection

摘要

A circuit uses a pair of transistors in series to provide an output pulse which indicates an address transition has occurred. A duration of joint conductivity of the pair of transistors determines the duration of the output pulse. For an address transition, one of the transistors is rapidly turned on while the other is slowly turned off with a slow fall time. The fall time is adjustable to achieve an adjustable duration of joint conductivity, and thereby an adjustable output pulse width.
