چکیده انگلیسی
A low voltage low power receiver supporting 780/868/915/2400â¯MHz ZigBee bands is presented in this paper. The receiver exploiting low-IF architecture consists of a RF-to-BB (baseband) current reuse front-end, a Gm-C based variable gain complex band-pass filter (CBPF) for image rejection and four stages of limiting amplifiers which saturate IF signal for demodulation. The proposed ZigBee receiver chip is implemented in TSMC 180â¯nm CMOS technology with metal-insulator-metal (MIM) capacitors. PCB measurement results show that the receiver has 45.9â¯dB conversion gain, 8.5â¯dB NF and â33.5â¯dBm out-of-band IIP3 at sub-GHz bands. When working in 2.4â¯GHz band, the gain is 38.4â¯dB, noise figure (NF) is 16.7â¯dB and the out-of-band IIP3 is â28.2â¯dBm. The S11 bandwidth (S11â¯<â¯â10â¯dB) can cover the entire ZigBee spectrum (700-2500â¯MHz). The receiver consumes 1.42â¯mW from a 1â¯V DC supply and the die size is 1.41â¯mm2 including all pads.
