Abstract :
In this paper, we propose a high performance radio frequency (RF) transmitter (Tx) with low-power and high data-rate features. The proposed circuit, which is dedicated to wireless interface to a network of medical sensors, uses a new Frequency Shift Keying (FSK) modulation technique and operates in the North American 902-928 MHz ISM Band. The proposed Tx was validated through post-layout simulations in 90nm CMOS technology. Using the proposed modulation technique, the transmission circuits without the local oscillator and the power amplifier consume no DC current which reduces the total power budget to 0.084 nJ/b achieving a data-rate of 20 Mb/s.
