摘　　要：介绍了一种适用于背板信号传输的连续时间均衡器(EQ),给出了电路的增益表达式。该电路数据传输速率可达到1.25Gb/s。采用0.18μm CMOS工艺对电路进行仿真,结果表明,电路自举因子为6dB和12dB,分别支持50mm和100mm的FR4背板信号传输。A continuous-time equalizer for backplane signal transmission was presented. The expression of circuit gain was given. The circuit bad a data transmission rate up to 1.25 Gb/s. Simulation based on 0. 18 μm CMOS process showed that the proposed equalizer had a boost factor of 6 dB and 12 dB, which supports signal transmission on 50 mm and 100 mm FR4 backplanes, respectively.
