چکیده

Low power, high-speed bus architectures, based on low swing voltage technique, using multithreshold voltage transistors are proposed in this paper. Three different classes of driver/repeater/receiver circuits are introduced. The driver circuits are comprised of high threshold voltage MOSFET transistors, in order to reduce their output swing level voltage. For re-pulling up the low swing voltage to full swing, innovated high-speed, cross-coupled latch, voltage receiver circuits are used. In applications having high load capacitance due to long interconnections, novel repeater circuits based also on multithreshold voltage technology are introduced. Using 0.5 lm multithreshold voltage process technology and 1 V supply voltage, SPICE measurements showed up to 45% improvement in the power delay product. 2004 Elsevier Ltd. All rights reserved.

A New Low-Voltage, Low-Power and High-Slew Rate CMOS Unity-Gain Buffer

Class-AB circuits, which are able to deal with currents several orders of magnitude larger than their quiescent current, are good candidates for low-power and high slew-rate analog design. This paper presents a novel topology of a class AB flipped voltage follower (FVF) that has better slew rate and the same power consumption as the conventional class-AB FVF buffer previously presented in liter...

High Speed Delay-Locked Loop for Multiple Clock Phase Generation

In this paper, a high speed delay-locked loop (DLL) architecture ispresented which can be employed in high frequency applications. In order to design the new architecture, a new mixed structure is presented for phase detector (PD) and charge pump (CP) which canbe triggered by double edges of the input signals. In addition, the blind zone is removed due to the elimination of reset signal. Theref...
