In this paper a low-power design of an integrated RF receiver for Wireless Sensor Networks (WSNs) in 90 nm CMOS technology is proposed. The receiver is IEEE 802.15.4 physical specifications compliant. It is designed to operate in ISM band at 2.45 GHz center frequency. Target devices for this kind of transceiver are low-cost battery powered smart embedded devices and sensors. The receiver is designed...
This paper presents the behavioral level modeling and circuit implementation of a flexible algorithmic ADC that can be used for Bluetooth and CDMA2000-1X receivers, and sensor applications. An accurate behavioral level model of the ADC has been implemented in Matlab/Simulink, including the most important circuit non-idealities. This model allows exhaustive behavioral simulations, to achieve an optimal...
This paper presents a fully integrated receiver front-end for a 2.4 GHz RF transceiver. A system level design for the radio front end for which these components are designed is also presented. The proposed receiver front end (Low-Noise Amplifier, Single-to-Differential Converter and Mixer) is based on a direct conversion architecture designed in 0.18 mum CMOS technology. It takes advantage of on-chip...
