Termination resistor作用

Web17 Oct 2024 · The advantage of the split termination is that it provides a low impedance path to ground for common mode noise. Differential signals see the termination resistor as the input impedance of the amplifier. Common mode signals (usually noise) do not create any voltage difference across the single termination resistor in the unsplit version. Web1 Nov 2007 · Fig. 1. Basic termination is accomplished with one of two methods: parallel or series. Resistive termination requires a resistor value that matches the characteristic impedance of the transmission line. Most …
