Survey on Analysis of Power Efficient Transmitter and Receiver of WSN

A more advanced description communication system has improved the research of WSN power-efficient transmitters (PETx) and power-efficient receivers (PERx) implemented. Many low power approaches have also been used to decrease power dissipation and improve power efficiency. The sensors and the PETx are interfaced via a low power microprocessor. To cut down on standby power, the sensors and PETx are power gated. The maximum system power consumption occurs when the SOC is operating in full functioning mode (i.e., the CPU, image processing, and wireless communication are all active at the same time) in a nanoscaled CMOS process. Low power design and approaches are also used to increase battery life. For the advancement of WSN, a low power efficient Tx and Rx has been developed, and 180nm, 130nm, and 90nm CMOS technologies have been compared. Analog and digital signal processing are also supported by these devices. These systems are widely employed in many fields, including industry, science, medicine, and the military, as a result of their characteristics.
