Applications of Zigbee SoC with low power based on full swing gate diffusion input [articol]

Abstract

ZigBee system-on-chip (SoC) is an essential module in all advanced wireless communication devices and it is the alternating advanced technology over the conventional Bluetooth technology. System on chip (SoC) is to develop complex network products fastly, easily and reliably which enable the end-users. A new implementation technique of efficient Xnor delay based encoder using full swing Gate-Diffusion-Input (GDI) technique is presented. Xnor circuit is the most energy efficient and very suited to low voltage application designs. This full swing GDI based encoder design allows reducing power and delay of the circuit, while maintaining low complexity of logic design. It minimizes the number of bit “1”s in modulated bit stream without losing information combined with full swing GDI logic style. Performance analysis is based on delay and power dissipation, advantages and drawbacks of full swing GDI encoder.
