A 2.4GHz hybrid PPF based BFSK receiver with ±180ppm frequency offset tolerance for wireless sensor networks
A low-power 2.4GHz 1Mb/s hybrid polyphase filter (PPF) based BFSK receiver with ±180ppm frequency offset tolerance (FOT) and 40dB adjacent channel rejection (ACR) at a modulation index (MI) of 2 is presented. High FOT at low MI is achieved by a frequency-to-energy conversion architecture using PPFs without any frequency correction. The proposed hybrid topology of the PPF provides an improved ACR at reduced power. The prototype receiver fabricated in a 0.13μm CMOS process, including RF and analog front-ends, consumes 1.95mW from a 1V supply with -84dBm sensitivity.
