|
In this paper, analysis and design of colpitts
oscillator with ability to transmit data at low output power with
application in short-range wireless sensor networks such as MICS
is described. Reducing the area required to implement the
transmitter, on-chip implementation and appropriate energy
efficiency are the advantages of this structure that makes it
suitable for the design of short-range transmitter in biomedical
applications. The proposed OOK transmitter works at 405 MHz
with 10 Mbps data rate. Output power and total power
consumption are 25 µW and 726 µW, respectively. Energy
efficiency is 72.6 pJ/bit. The transmitter has been designed and
simulated in 0.18 µm CMOS technology.
