摘　　要：首先指出了 ECL电路随着集成度和速度的提高 ,存在着功耗太大的问题 ,进而提出了采用低电压电源以降低功耗 ,为此发展了将串联开关转换成并联开关的技术 ,保证了电路能在低电压下正常工作 ,并由此实现了适合于低电压工作的 ECL电路的开关级设计。从对设计的电路进行的计算机模拟结果表明 ,采用文中提出的并联开关技术设计的电路 ,在电源电压为 -2 .5 V时 ,不仅具有正确的逻辑功能和较高的工作速度 ,且比采用-5 .0 V电源的电路节约了 80In this paper, the problem of high power dissipation of ECL integrated circuits with the increase of the speed and density is discussed. Then, we propose to use low-voltage supply to decrease power dissipation for ECL circuits and develop a parallel switches technique instead of cascade switches to make ECL circuits operate correctly at low-voltage supply. Using this technique, ECL circuits which can operate at low-voltage supply can be designed at switch-level. The simulation results show that the designed ECL circuits with -2.5 V supply voltage using the parallel switches technique proposed not only have correct logic functions and high speed, but also decrease more than 80% power dissipation comparing with the counterparts with -5 V supply voltage.
