Abstract

See full text

A coupling system in an integrated circuit to block DC components from an amplifier without large costly external coupling capacitors. An input receives an input signal which has a DC component. A first impedance element receives the input signal and blocks the DC component while a second impedance element connects between the output of the first impedance matching element and a ground node. The second impedance element and the first impedance element form a voltage divider network. The first and second impedance element are integrated elements. The amplifier receives the input signal after the DC component is blocked. The first impedance element and the second impedance element may comprise a resistor in series with a capacitor. In a differential pair configuration, an impedance matching element interconnects between a first path and a second path to impedance match the amplifier to a data source.
