Abstract

Various embodiments of the present invention relate to circuits for and methods of generating a bias current for a plurality of data transceivers on an integrated circuit. According to one embodiment, an integrated circuit having a plurality of data transceivers comprises a first data transceiver receiving a reference voltage. A plurality of data transceivers are preferably coupled to the first data transceiver, where each the data transceiver of the plurality of data transceivers receives a reference current based upon the reference voltage from the first data transceiver. According to alternate embodiment of the invention, an external resistor is coupled to a data transceiver to generate a fixed bias current in addition to a variable bias current. A method of generating a bias current for a plurality of data transceivers is also disclosed.
