  • Low voltage differential signalling driver
    Patent number: 7551006
    Abstract: A low voltage differential signal (LVDS) driver comprising a cascade current source circuit coupled to a positive voltage supply configured to supply a current, a cascade current sink circuit maintained at a ground voltage configured to receive the current; the cascade current source circuit being coupled to the cascade current sink circuit by a current switching circuit being provided by a positive voltage supply from the cascade current source circuit and with complementary logic signals, the current switching circuit configured to provide a constant differential output voltage while in operation. Other embodiments are also disclosed.
