Abstract :
The aim of the 2.4GHz front-end receiver presented in this paper is the minimization of both cost and energy consumption, focusing on WPAN IEEE 802.15.4 transceivers. It includes the entire RF part, from the balun to the first stage of the channel filter, as well as the LO signal conditioning cells. The proposed architecture uses an unmatched inductorless LNA and a new clocking scheme on a standard passive mixer. Compared to previously reported IEEE 802.15.4 receivers, an area reduction by at least 70% is achieved. The power consumption is relatively low at 5.4mW with a state-of-the-art noise and linearity performance. The receiver front-end operates at 1.35V. It is implemented in a 90nm CMOS technology using two thick metals, and alucap with RFMOM capacitors.
