Abstract :
An analog bias circuit consisting of two transistors, three current sources, and one resistor facilitates the design of an Ethernet line driver. The rise time is insensitive to process variations and temperature variations, Rise-time accuracy is 223 ppm/°C over a temperature range of 140°C. This line driver has been fabricated in 0.35-μm CMOS
