Abstract: A 2.4 GHz reference-less single chip wireless receiver for 1 Mbps QPSK demodulation is presented. The receiver accomplishes LO carrier recovery and data demodulation directly from the RF received signal without resort to resonator based reference, such as crystal oscillator. Integrating LNA, mixer, LO carrier recovery loop, postamplifier, and digital demodulator on a single chip, the total power consumption is 20.4 mW. The measured phase noise from a recovered carrier at 2.432 GHz is about -111 dBc/Hz at 1 MHz offset. The chip size is 1.75 x 1.55 mm(2).
