This paper presents a burst-mode receiver for 1.25-Gb/s Ethernet PON system using mixed-mode CMOS 0.18-/spl mu/m technology. With the modified cell-based AGC function and differential feed-forward topology, the receiver achieves sensitivity of -26.4 dBm, overload of -5.4 dBm, and a loud/soft ratio of 21 dB while keeping the low-voltage positive emitter-coupled logic (LVPECL) differential output level fully compliant with the ethernet passive optical network (EPON) standard. Unlike other burst-mode receivers, the design obtains fast response even without a reset signal from the network layer by creating a reset signal internally based on the incoming signal. This setting allows for simple system design. The overall architecture and several blocks are optimized in accordance with internal reset creation. Minimum guard time and preamble time are 250 and 50 ns, respectively; all timing parameters are better than the current EPON standard. The prototype contains all components on-chip that occupies 0.9/spl times/1.9 mm/sup 2/ and consumes 160 mA current from a 3.3-V supply.
