A 1.8V transmitter for 10/100 Mbps Ethernet physical layer

In English A 0.18 mum 1.8 V CMOS transmitter for 10/100Mbps Ethernet physical layer standards is described in this paper. The circuit is substantively a current-steering digital-to-analog converter with 5-bit resolution, 125MHz sample rate and 4ns transition time. A novel latch circuit is designed, as well as a structure is provided to realize the accurate rise/fall time control of waveform
