Claim:
1. A slope control circuit, electrically connected between a replica circuit and a controller area network bus, wherein said replica circuit generates an upper feedback signal and a lower feedback signal, and said slope control circuit receives and is driven by said upper feedback signal and said lower feedback signal so as to control a voltage slope of a high-level output and a low-level output of said controller area network bus, said slope control circuit comprising: an upper driving circuit, connected between said replica circuit and said high-level output and comprising at least one first charging and discharging circuit, in which said first charging and discharging circuit is controlled in association with a decreasing voltage slope of said high-level output; and a lower driving circuit, connected between said replica circuit and said low-level output and comprising at least one second charging and discharging circuit, in which said second charging and discharging circuit is controlled in association with a increasing voltage slope of said low-level output such that said decreasing voltage slope of said high-level output and said increasing voltage slope of said low-level output are symmetric.
