Patent number: 6504403Abstract: Problems associated with using bipolar differential circuits over a wide common mode voltage range are solved using first and second amplifier circuits 3 and 5, respectively operating over first and second voltage sub-ranges. The low voltage differential signal (LVDS) 1 is applied across a pair of series connected resistors 7 and 9, and to the inputs of the amplifiers 3 and 5. The common mode voltage signal 11 is fed to the inputs of third and fourth amplifiers 15 and 17. The third and fourth amplifiers 15 and 17 ensure that the LVDS receiver has a constant linear transfer characteristic over the differential input signal range and over the full common mode range, especially over the amplifier transition region.Type: GrantFiled: December 19, 2000Date of Patent: January 7, 2003Assignee: Telefonaktiebolaget LM EricssonInventors: Joakim Bängs, John Thompson, Raymond Filippi
