A Direct Down-conversion Receiver for Low-power Wireless Sensor Networks

Tijdschriftbijdrage - Tijdschriftartikel

A direct downconversion receiver implemented in
0.13 um 1P8M process is presented. The circuit is formed by a
single-end LNA, an active balun for conversion into balanced mode,
a quadrature double-balanced passive switch mixer and a quadrature
voltage-controlled oscillator. The receiver operates in the 2.4 GHz
ISM band and complies with IEEE 802.15.4 (ZigBee) specifications.
The circuit exhibits a very low noise figure of only 2.27 dB and
dissipates only 14.6 mW with a 1.2 V supply voltage and is hence
suitable for low-power applications.
