Analysis and Design of 8-Bit CMOS Priority Encoders

چکیده
A comprehensive review and fair comparison of previous priority encoder (PE) designs over the past one and a half decades are presented using a 45 nm technology. Further, potential limitations of existed PEs are identified, based on which we propose a robust PE design. The new PE is able to eliminate race condition and charge sharing problem which are su↵ered by almost all the previous designs. Besides, the proposed PE can also be used in comprising higher order PEs by incorporating a carefully designed look-ahead structure. Simulation results demonstrate that our design can achieve one of the best power and delay performance among previous PEs and are free from potential risks.

High-Speed and Low-Power Flash ADCs Encoder
This paper presents a high-speed, low-power and low area encoder for implementation of flash ADCs. Key technique for design of this encoder is performed by convert the conventional 1-of-N thermometer code to 2-of-M codes (M = ¾ N). The proposed encoder is composed from two-stage; in the first stage, thermometer code are converted to 2-of-M codes by used 2-input AND and 4-i...
متن کاملA VLSI High-Performance Encoder with Priority Lookahead
In this paper we introduce a VLSI priority encoder that uses a novel priority lookahead scheme to reduce the delay for the worse case operation of the circuit, while maintaining a very low transistor count. The encoder's topmost input request has the highest priority; this priority descends linearly. Two design approaches for the priority encoder are presented, one without a priority lookahead ...

متن کاملLow-Power Adder Design for Nano-Scale CMOS
A fast low-power 1-bit full adder circuit suitable for nano-scale CMOS implementation is presented. Out of the three modules in a common full-adder circuit, we have replaced one with a new design, and optimized another one, all with the goal to reduce the static power consumption. The design has been simulated and evaluated using the 65 nm PTM models.
