A new analog equalizer supporting 10Base-T central office and remote terminal (Category-3) LAN applications is developed. It provides robust 10 Mbps data transmission (10Base-T) at loop length up to 400 meters. The equalizer with high frequency gain boost capability is controlled automatically by the proposed AZC (Adaptive Zero Control) loop according to cable length. It is implemented using AMS 0.8 µm CMOS technology.
