Abstract

A broad range of new high-volume consumer applications require the availability of low-power, battery operated, wireless microsystems and sensors. For such applications, a fully integrated receiver based on a direct conversion architecture was designed and realized in a standard 0.5 μm digital CMOS process with 0.6 V threshold voltage. It uses FSK modulation in the 434 MHz ISM band, and operates with only 1 V supply, allowing it to be powered by a single battery cell. It achieves a -95 dBm sensitivity for a data rate of 24 kbit/s and an ultralow power consumption of only 1 mW
