摘要
本文叙述了全温(-55~+125℃)超高速ECL双模预置分频器的工作原理、电路设计、版图设计及研制结果,还简述了制作工艺。整个电路设计以提高电路工作速度和温度特性为中心,采用优化的开关电流分配、最佳的电路工作点设置、带温度补偿的电阻反馈网络结构和合理的版图设计,来提高工作速度和保证良好的温度性能。研制的÷8/9分频器,在全温范围内最高工作频率达600MHz以上。
The principle of operation, circuit and layout design of a very high speed ECL bim-odal prescaler in full temperature range ( -55℃-+125℃) are described in the paper, together with results of the develoment. A brief introduction of the fabrication process is made. The circuit design is centered on increasing operation speed and improving temperature behavior, which have heen achieved with optimized switching current distribution, optimal setup of working points, temperature compensated resistor feedback network and reasonable layout design. A ÷8/9 frequency divider has been fabricated, whose maxium operating freqency in full temperature range is stable at 600MHz and above.
