Abstract
An LVDS receiver of the present invention rapidly restores an LVDS inputted at a high speed into a full swing signal of CMOS or TTL level. A common mode shifter amplifies an LVDS contained in a common mode signal and then shifts a level of the common mode signal. Further, an intermediate amplifying unit amplifies a signal outputted from the common mode shifter to have a margin above and below a threshold voltage in a predetermined logic lever. In addition, an output buffer unit amplifies a signal outputted from the intermediate amplifying unit to produce a full swing signal.
Claims12
A low voltage differential signal (LVDS) receiver, comprising:
- a common mode shifter for shifting a level of a common mode signal and amplifying an LVDS contained in the common mode signal;
- an intermediate amplifying unit for amplifying a signal outputted from the common mode shifter;
- and
- an output buffer unit for amplifying a signal outputted from the intermediate buffer unit to produce a full swing signal.
