Abstract

In the transmitter of optical communication systems, a time-division multiplexer combines several parallel data streams into a single data stream with a high bit rate. In this paper, we design a 4:1 (4-channels) time-division multiplexer using SiGe HBT with emitter size of 2x8um2. The operation speed is 100bps, the rise and fall times of 20-80% are 34ps and 34ps, respectively and the dissipation of power is 1.50W.

시분할 멀티플렉서는 여러 병렬 스트림(stream)들을 높은 비트율을 갖는 하나의 직렬 스트림으로 결합하는 장치로, 광통신 시스템의 송신부에 사용된다. 본 논문에서는 에미터 크기가 2$\times$8um\sup 2\인 SiGe HBT를 사용하여 4:1 (4채널) 시분할 멀티플렉서를 설계하였다. 설계된 회로의 동작속도는 10Gbps, 입력전압 및 출력전압은 각각 400mVp-p와 800mVp-p, 20-80% 간의 상승시간 및 하강시간은 각각 34ps와 34ps이며, 전력소모는 1.50W이다.
