چکیده
In this paper we propose a methodology to design high-speed, power-efficient static frequency dividers based on the low-voltage Folded MOS Current Mode Logic (FMCML) approach. A modeling strategy analyze dependence of propagation delay and power consumption bias currents divide-by-2 (DIV2) cell is introduced. We demonstrate that behavior FMCML DIV2 different both from one conventional MCML DFF (D-type Flip-Flop) without level shifter. Then an analytical optimize divider in scenarios: maximum speed, minimum power-delay product (PDP) or energy-delay (EDP) presented. The possibility scale through stages affecting speed performance also investigated. proposed approach allows gain deep insight into circuit comprehensively tradeoffs. derived models guidelines are validated against transistor simulations referring commercial 28nm FDSOI CMOS process. Different divide-by-8 circuits following optimization strategies have been designed same technology showing effectiveness methodology.

Low-Voltage MOS Current Mode Logic Multiplexer
In this paper, a new low-voltage MOS current mode logic (MCML) multiplexer based on the triple-tail cell concept is proposed. An analytical model for static parameters is formulated and is applied to develop a design approach for the proposed low-voltage MCML multiplexer. The delay of the proposed low-voltage MCML multiplexer is expressed in terms of the bias current and the voltage swing so th...

This paper investigates important problems involved in the design of a CML buffer as well as a chain of tapered CML buffers. A new design procedure to systematically design a chain of tapered CML buffers is proposed. The differential architecture of a CML buffer makes it functionally robust in the presence of environmental noise sources (e.g., crosstalk, power/ground noise). The circuit design ...

متن کاملDesign of A Low - Voltage and Low - Power Voltage Mode
A low-voltage and low-power voltage mode adder/subtractor using MOSFETs in weakinversion is presented in this paper. Since the MOSFETs in the proposed circuit are biased in weak inversion, consequently its power dissipation is very low. The proposed circuit has been simulated with the HSPICE using a N-well 0.35μm 2p4m process and the results show that, under the supply voltage of 1V, the power ...
