FULL SWING VOLTAGE INPUT/FULL SWING VOLTAGE OUTPUT BI-DIRECTIONAL REPEATERS FOR HIGH RESISTANCE OR HIGH CAPACITANCE BI-DIRECTIONAL SIGNAL LINES AND METHODS THEREFOR

摘要

A bidirectional full swing voltage repeater implemented on a signal line of an integrated circuit, which includes a first enable node for providing a first enable signal and a second enable node for providing a second enable signal. There is included a first full-swing unidirectional repeater circuit coupled between a first portion of the signal line and a second portion of the signal line. The first full-swing unidirectional repeater is configured to pass a first full swing signal from the first portion of the signal line to the second portion of the signal line when the first enable signal is enabled. The second full-swing unidirectional repeater circuit is coupled between the first portion of the signal line and the second portion of the signal line. The second full-swing unidirectional repeater circuit is configured to pass a second full swing signal from the second portion of the signal line to the first portion of the signal line when the second enable signal is enabled, wherein the first full-swing unidirectional repeater circuit and the second full-swing unidirectional repeater circuit are tri-stated when both the first enable signal and the second enable signal are disabled.
