Abstract:
1. A low voltage differential signaling driver comprising: first and second current sources; a first branch, which comprises at least two transistors and at least two resistors therebetween that are all connected in series between the first and second current sources to define a first node between adjacent resistors that is configured to transmit and receive a first signal; a second branch, which comprises at least two transistors and at least two resistors therebetween that also are all connected in series between the first and second current sources to define a second node between adjacent resistors that is also configured to transmit and receive a second signal; and a control switch connected between the first branch and the second branch, which controls the transmission and reception of the first and second signals, wherein the first signal and the second signal are differential signals; wherein the first branch comprises: wherein the second branch comprises: wherein the control switch is connected between a third node and a fourth node, the third node connecting the first transistor and the first resistor and the fourth node connecting the third transistor and the third resistor.
