Abstract:
1. A receiver comprising: a first transmission line providing a first input signal; a second transmission line providing a second input signal; a signal reception circuit connected to the first transmission line and the second transmission line, said signal reception circuit including a first amplifier section configured to generate a first current in response to the first input signal and a second amplifier section configured to generate a second current in response to the second input signal, to thereby generate an amplification signal in accordance with a difference between said first and second currents; and a feedback signal generating circuit connected to said signal reception circuit and configured to generate a feedback signal in accordance with said amplification signal, driving abilities of said first and second amplifier sections being determined in accordance with said feedback signal, wherein said amplification signal is formed by a non-inverted amplification signal and an inverted amplification signal, so that said signal reception circuit comprises a non-inverted amplification signal generating circuit and an inverted amplification signal generating circuit, said first current being formed by a first non-inverted-side current and a first inverted-side current, said second current being formed by a second non-inverted-side current and a second inverted-side current, said non-inverted amplification signal generating circuit comprising: a first non-inverted-side current generating section as said first amplifier section adapted to generate said first non-inverted-side current in response to said first input signal; and a second non-inverted-side current generating section as said second amplifier section adapted to generate said second non-inverted-side current in response to said second input signal; said non-inverted amplification signal being generated in accordance with a difference between said first and second non-inverted-side currents, driving abilities of said first and second non-inverted-side current generating circuits being determined in accordance with said feedback signal, said inverted amplification signal generating circuit comprising: a first inverted-side current generating section as said second amplifier section adapted to generate said first inverted-side current in response to said second input signal; and a second inverted-side current generating section as said first amplifier section adapted to generate said second inverted-side current in response to said first input signal; said inverted amplification signal being generated in accordance with a difference between said first and second inverted-side currents, driving abilities of said first and second inverted-side current generating circuits being determined in accordance with said feedback signal.
