ANALYSIS OF MOS CURRENT MODE LOGIC (MCML) AND IMPLEMENTATION OF MCML STANDARD CELL LIBRARY FOR LOW-NOISE DIGITAL CIRCUIT DESIGN

This paper proposes hybrid dynamic current mode logic (H-DyCML) as an alternative to existing dynamic CML (DyCML) style for digital circuit design in mixed-signal applications. H-DyCML introduces complementary pass transistors for implementation of logic functions. This allows reduction in the stacked source-coupled transistor pair levels in comparison to the existing DyCML style. The resulting reduction in transistor pair levels permits significant speed improvement. SPICE simulations using TSMC 180 nm and 90 nm CMOS technology parameters are carried out to verify the functionality and to identify their advantages. Some issues related to the compatibility of the complementary pass transistor logic have been investigated and the appropriate solutions have been proposed. The performance of the proposed H-DyCML gates is compared with the existing DyCML gates. The comparison confirms that proposed H-DyCML gates is faster than the existing DyCML gates.

The economic and efficient accomplishment of an application-specific integrated circuit design depends heavily upon the choice of the library. Therefore, it is important to build library that full fills the design requirement. Tanner Tools is a set of software for designing integrated circuits. The great advantage of Tanner is that it can provide a complete circuit design tools in desktop computers. The paper aims to create a standard cell library establishment on the 0.5 micro complementary metal–oxide–semiconductor mixed signal process based on the Tanner Tools.

Current Mode Logic

In this paper, a logic style that is becoming increasingly popular is presented, which is called MOS Current Mode Logic (MCML). MCML is a novel and useful logic style for high-speed, low-power and mixed-signal applications. Its high-speed switching, low supply voltage and reduced output voltage swing contribute to its high performance, low power dissipation, and low noise features. MCML circuits are compared to several other logic styles, such as conventional static CMOS, dynamic logic, and traditional emitter coupled logic (ECL) in terms of power, delay and common mode noise immunity. MCML circuits seem to be very promising in high-speed, low-power and mixed-signal digital circuit applications, such as portable electronic devices, gigahertz microprocessors, and optical transceivers.
