Abstract
RF circuitry, which includes a first passive voltage-gain network and a first MOS-based RF receive amplifier, is disclosed. The first passive voltage-gain network provides a first passive RF receive signal using a first RF receive signal, such that an energy of the first passive RF receive signal is obtained entirely from the first RF receive signal by the first passive voltage-gain network. A voltage of the first passive RF receive signal is greater than a voltage of the first RF receive signal. The first MOS-based RF receive amplifier receives and amplifies the first passive RF receive signal to provide a first amplified RF receive signal.
