Design automation for differential MOS current-mode logic circuits, 1st ed. 2019

In state-of-the-art mixed-signal integrated circuits and systems design, the co-existence of very high speed digital blocks and very high-sensitivity analog blocks is one of the key design problems. The substrate and power supply noise that is generated by the conventional CMOS digital blocks in a mixed-signal integrated circuit inevitably influence the operational characteristics of the analog blocks. Therefore, considerable attention is being devoted in recent years to the design of alternative logic circuit styles that do not generate excessive amounts of switching noise at high operating frequencies. MOS Current-Mode Logic (MCML) is one of the emerging logic styles that can allow very high frequency operation with very low switching noise, and thus it is a natural candidate for implementing digital blocks in mixed-signal systems. Design Automation for Differential MOS Current-Mode Logic Circuits provides a very detailed and comprehensive analysis of fundamental MCML circuits, their design and performance optimization under competing constraints such as output drive capability, power dissipation, noise margin, and silicon area. A systematic methodology is presented to build efficient MCML standard-cell libraries, and a complete top-down design flow is shown to implement complex systems using such building blocks. As such, Design Automation for Differential MOS Current-Mode Logic Circuits presents one of the first-ever top-down design approaches using differential cells, for high performance and low noise operation.
