Abstract :
This paper presents RF microsystems constituted by low-power devices for use in wireless sensors networks. As it is expected, the major emphasis is given to the fabrication of RF transceivers for integration in these microsystems. Features like low-power and low-voltage operations are discussed, at the same time are presented RF transceivers for the frequencies of 433 MHz, 2.4 GHz and 5.7 GHz, in order to comply with mandatory issues of WSN, e.g., working independently from a human operation, management and maintenance. Another reason for this, is the suitableness of these wireless microsystems to use thermoelectric energy scavenging systems.
