Document Type and Number:
Japanese Patent JP2012161077
Kind Code:
A
Abstract:

To provide a pre-emphasis circuit and differential current signal transmission system having the same.

The present invention relates to a pre-emphasis circuit and particularly to a pre-emphasis circuit capable of preventing generation of an unwanted current by reducing the number of switching transistors required for operating the pre-emphasis circuit to reduce the number of parasitic resistances and parasitic capacitors and by supplying each pre-emphasis control signal for controlling the each switching transistor, and to a differential current signal transmission system having the same.
