Abstract
In this paper, we proposed a new structural AGC(Automatic Gain Control) circuit with extremely short settling time using high speed operation characteristics of a clipper. We investigated its operation characteristics in analysis. We also designed a burst-mode preamplifier for 1.25Gbps EPON systems using commercial foundry and investigated its characteristics by comparing the results of the designed and those of the analyzed. The characteristics of the designed circuit are in good agreement with those of the analyzed. As a result, it is shown that it is possible to realize extremely short settling time of under 1㎱.
