Signal transmitting circuit

摘要

A signal transmitting circuit includes a driving circuit, and a plurality of receiving circuits receiving signals transmitted from the driving circuit. Each of the receiving circuits is coupled to the driving circuit consecutively via a transmission line. A voltage regulator is coupled to the driving circuit and the receiving circuits and provides power to the driving circuit and the receiving circuits. A number of capacitors are coupled between the voltage regulator and the ground for filtering the noise of the power output from the voltage regulator. The capacitors between the voltage regulator and the north bridge chipset filtering the noise of the power output from the voltage regulator maintain signal integrity as the terminal resistor does. It is of advantage that the signal transmitting circuit is simple to manufacture and very suitable for mass production.
