Abstract

A single-chip tunable CMOS low-IF single-conversion receiver operated in the 915-MHz ISM band is proposed. A new 10.7-MHz IF section including a limiting amplifier and FM/FSK demodulator is employed. Near IF section sensitivity of -72 dBm, the demodulation constant of FM/FSK demodulator is 15 mV/kHz and the dynamic range of the limiting amplifier reaches 80dB. With on-chip tunable components in low power LNA and LC-tank VCO circuit, the receiver measures a RF gain of 15dB at 915-MHz, sensitivity of -80dBm at 0.1% BER, IIP3 of -9dBm, and NF of 5dB with current consumption of 33mA and a chip area of 6 mm²
