Abstract

A 2.4 GHz reference-less single chip wireless receiver for 1Mbps QPSK demodulation is presented. The receiver accomplishes LO carrier recovery and data demodulation directly from the received RF signal without resort to resonator based reference, such as crystal oscillator. Integrating LNA, mixer, LO carrier recovery loop, post amplifier, and digital demodulator on a single chip, the total power consumption is 20.4mW. The measured phase noise from a recovered carrier at 2.432 GHz is about -112 dBc/Hz at 1 MHz offset. The chip size is 1.75 x 1.55 mm2.
