Conventional AGC circuit is inappropriate for BMU data transmission because it is based on average level detection and requires considerable time to settle on a predefined gain. Therefore, we adopt a fast switched-mode AGC based on peak level detection. After the gain is adjusted, the peak level detectors need to re-detect the peak level of the input signal. Thus, we develop an internally created reset module. This AGC with reset module exhibits a fast operation and achieves an adjusted stable gain within one-bit, avoiding any bit loss up to 10Mb/s data rate. During power-up, the peak level detectors possibly hold an uncertain level resulting in the bit-errors. We propose a power-up reset circuit to solve this problem. Designed in a 0.5μm CMOS technology, the circuit achieves an optical sensitivity of better than -30dBm and a wide dynamic range of over 30dB with a power dissipation of only 30 mW from a 5V supply.展开更多

Nanshu Town has 46 graphite enterprises with scattered distribution, incomplete industry chain, low output, and low value-added. In order to exert the resources advantage, Nanshu Town has planed and builta building materials zone covering 800 thousand square meters since 2010. Kaonuo Ceramics, a key project of Qingdao City, was building here. Three deep-processing projects of graphite new materials with the total investment of CNY 480 million will be built in this zone.展开更多
