摘要：
A line driver outputs a pair of transmit signals TX+ and TX− that have substantially reduced output level variations due to variations in process, voltage, and temperature. The reduced output level variations are provided by varying the magnitude of the current that sets up the voltages of the transmit signals in a manner that offsets variations in the power supply voltage, temperature, and process, and by limiting variations of the bandgap current source to process and temperature only.
