Title: CMOS small signal switchable, impedence and voltage adjustable terminator network and receiver integration

Abstract: A terminator circuit for connection to a network can be fabricated and used within CMOS-SOI (complementary metal oxide semiconductor--silicon on insulator) for carrying small logic level signals for connecting data from a network's first circuit to a network's second circuit in which a network's input terminal connects a terminator circuit to the network's second circuit to act as a terminator on the data line passing data from said first circuit to said second circuit. The terminator circuit has a reference circuit coupled to a terminal circuit. An adjustment section provides an impedance adjustment and adjustment circuits for tuning the center voltage of the incoming voltage swing up and down. A differential receiver has a stable and well centered threshold voltage is coupled to the network input terminal for connecting the network's first circuit to the network's second circuit.
