BANDWIDTH-BOOSTED BIDIRECTIONAL SERIAL BUS BUFFER CIRCUIT

Abstract:

A serial bus buffer circuit includes a master input-output terminal, a slave input-output terminal, a switched resistor circuit, and a switch control circuit. The switched resistor circuit is configured to provide a low impedance connection between the master input-output terminal and the slave input-output terminal. The switch control circuit is coupled to the switched resistor circuit, and is configured to enable the low impedance connection based on voltage at the master input-output terminal and voltage at the slave input-output terminal.
