A constant slew-rate Ethernet line driver

A biasing technique is described that facilitates the design of a fast Ethernet line driver. The slew rate is insensitive to temperature and process variations. The core-biasing block consists of three current sources, a resistor, and two transistors. 230 ppm/deg C temperature drift is achieved with...

Summary:A biasing technique is described that facilitates the design of a fast Ethernet line driver. The slew rate is insensitive to temperature and process variations. The core-biasing block consists of three current sources, a resistor, and two transistors. 230 ppm/deg C temperature drift is achieved without trimming.
