Abstract
Differential signaling transmitter circuitry includes upper and lower driver stacks, each with at least one upper blocking transistor and a bias transistor, further includes first and second control loops. A first control loop includes a replica stack including replicas of the bias transistor and blocking transistors of a first one of the driver stacks, and a second control loop includes replica stacks, one with replicas of the bias and blocking transistors of the upper driver stack and one with replicas of the bias and blocking transistors of the lower driver stack. One of the replica stacks in the second control loop receives an output from the first control loop. First and second switching circuitry couples outputs of the first and second control loops to gates of bias transistor in the upper and lower driver stacks, respectively, responsive to a data signal.
