Patent ID: 7030656

Claim:
A low voltage differential signaling (LVDS) transmitting device, comprising: a signal driving circuit for generating and outputting an analog image signal to an LVDS receiving device, comprising a differential signaling device including at least four transistors, a first current source including a transistor coupled between a power source and said differential signaling device, and a second current source including at least two transistors coupled between said differential signaling device and ground; and a signal compensation circuit in communication with said signal driving circuit, comprising: a voltage-to-current converting circuit for generating and outputting a compensation signal as a current type in response to said analog image signal and a base signal; and a first current mirror circuit and a second current mirror circuit for feeding said compensation signal back to said signal driving circuit, wherein said first current mirror circuit is coupled to said voltage-to-current converting circuit and ground, and said second current mirror circuit is coupled to said first current mirror circuit, a power source and a differential signaling circuit of said signal driving circuit, thereby compensating the current signal variation of said first current source so as to stabilize said analog image signal generated by said signal driving circuit.
