This paper explores the deterministic transistor reordering in low-voltage dynamic BiCMOS logic gates, for reducing the dynamic power dissipation. The constraints of load driving (discharging) capability and NPN turn-on delay for MOSFET reordered structures has been carefully considered. Simulations shows significant reduction in the dynamic power dissipation for the transistor reordered BiCMOS...

The overall view of this paper is to attain high speed, low power full adder cells with alternative logic cells that lead to have reduced power delay product. Two high-speed and low-power full adder cells designed with an alternative internal logic structure and pass-transistor logic styles that lead to have a reduced power-delay product (PDP). We carried out a comparison against other full-add...

This paper proposes a new design of 2T AND gate. Performance comparison of proposed gate with existing 2T GDI technique is presented. Different methods have been compared with respect to the number of devices, power consumption, power-delay product, temperature sustainability and noise immunity in order to prove the superiority of proposed design over existing 2T gate design. The simulation has...

A new CMOS buffer without short-circuit power consumption is proposed. The gatedriving signal of the output pull-up (pull-down) transistor is fed back to the output pull-down (pull-up) transistor to get tri-state output momentarily, eliminating the short-circuit power consumption. The HSPICE simulation results verified the operation of the proposed buffer and showed the power-delay product is a...

Subthreshold source-coupled logic (STSCL) circuits can be used in design of low-voltage and ultra-low power digital systems. This article introduces and analyzes new techniques for implementing complex digital systems using STSCL gates with an improved power-delay product (PDP) based on source-follower output stages. A test chip has been manufactured in a conventional digital 0.18μm CMOS techno...

In this paper, we present a 32bit Han-Carlson adder that operates at 2.56GHz and is based on TSMC 0.18um bulk CMOS technology. In this work, we optimize the substrate bias of the adder core to achieve a low power-delay product for low power and high speed purposes, and use a post-manufacture tunable clock structure that manipulates the clock at post-fabrication stage to compensate for the proce...

Recently low power circuits have become a top priority in modern VLSI design. This paper presents post layout simulations of a new improved 2:1 multiplexer design. The proposed design demonstrates its superiority against existing 2:1 multiplexer design in terms of power–delay product (PDP), temperature sustainability, noise immunity and frequency. All the post-layout simulations have been perfo...

Voltage scaling has been often used for reducing power dissipation of CMOS driven interconnects. An undesired effect observed due to voltage scaling is increase in propagation delay. Thus a trade off lies between power dissipation and propagation delay with voltage scaling. However, voltage scaling can result in overall reduction of power delay product (PDP). Therefore, their lies an optimized ...

The new logic family based upon the proposed design procedures has certain ad...

A new CMOS buffer without short-circuit power consumption is proposed. In this work, the gate-driving signal of the output pull-up (pull-down) transistor is fed back to the output pull-down (pull-up) transistor to get tri-state output momentarily, eliminating the short-circuit power consumption. The TSPICE simulations are used to verify the operation of the buffer. It is observed that the power...
