Abstract
An optical transmitter driver is disclosed to drive a load with a drive signal responsive to a first and second input signal. The differential pair includes a first path having a first resistor connected to a first voltage supply and to a first transistor that receives the first input signal. A second path includes a second resistor connected to a second voltage supply and a second transistor. The first voltage supply is less than the second voltage supply. The second transistor has an input configured to receive the second input signal and the first and second input signals define a differential signal. Also part of this embodiment is a load connection node that presents the drive signal to the load. The first voltage supply is less than the second voltage supply. In one configuration cross coupled capacitor are connect between each input and the first path and second path.
