A low-power, energy-efficient and configurable transceiver architecture is introduced. It is implemented on a single chip intended for use in short range radios based on WPAN (IEEE802.15.4) at 2.4 GHz. The circuitry employed in the dual conversion receiver with the tunable LNA is re-used in the dual loop frequency synthesizer to form a constant envelope modulator and function as the transmitter; techniques...
A low power and energy efficient transceiver architecture is introduced. It is implemented on a single chip intended for use in short range radios based on WPAN (IEEE 802.15.4) at 2.4 GHz. The transmitter is based on a constant envelope modulator built around a dual loop frequency synthesizer coupled through an injection locking mechanism. The core of the dual conversion receiver is realized by reconfiguring...
