Patent number: 8660439Abstract: A transimpedance amplifier for a burst mode optical communication converts a burst current signal into differential output voltage signals. Using a multi-level digital AGC mechanism, the transimpedance amplifier is rapidly adapted to a burst signal whose amplitude varies in a wide range. By using an adaptive level detection method, a multi-level digital AGC can be implemented without using ADC. In addition, because the transimpedance amplifier uses a selective reset generation scheme that performs a reset operation for itself after a high power burst, a burst mode operation can be performed without external reset signals. Accordingly, the transimpedance amplifier can be integrated with an optical detector within a TO-can. Furthermore, the transimpedance amplifier can have the burst mode capability and the best sensitivity.Type: GrantFiled: December 5, 2006Date of Patent: February 25, 2014Assignees: Electronics and Telecommunications Research Institute, Research and Industrial Cooperation GroupInventors: Ho-Yong Kang, Hyun-Kyun Choi, Quan Le, Yool Kwon, Bong-Tae Kim, Sang-Gug Lee
