摘要: An apparatus includes a radio-frequency (RF) receiver for receiving an RF signal using a plurality of antennas. The RF receiver includes a demodulator to provide a switch signal to cause the RF receiver to use an antenna in the plurality of antennas. The RF receiver further includes a carrier frequency offset (CFO) correction circuit that uses an estimation of the carrier frequency offset and an estimation of phase differences to remove the carrier frequency offset.

摘要: A radio-frequency (RF) apparatus includes a wideband receive (RX) impedance matching circuit to provide a received differential RF signal to RF receive circuitry. The wideband RX impedance matching circuit includes first and second inductors to receive the differential RF signal. The wideband RX impedance matching circuit further includes a third inductor coupled across an input o the RF receive circuitry. The third inductor performs the functionality of a capacitor having a negative capacitance value.

摘要: An apparatus includes a radio-frequency (RF) circuit, which includes a power amplifier coupled to receive an RF input signal and to provide an RF output signal in response to a modified bias signal. The RF circuit further includes a bias path circuit coupled to modify a bias signal as a function of a characteristic of an input signal to generate the modified bias signal. The bias path circuit provides the modified bias signal to the power amplifier.

摘要: An apparatus includes a radio frequency (RF) receiver. The RF receiver includes a timing correlator and frequency offset estimator. The timing correlator and frequency offset estimator: (a) extracts timing from a set of samples derived from an RF signal, and (b) determines a frequency offset estimate from the set of samples.

摘要: An apparatus includes an integrated circuit (IC), which includes complementary metal oxide semiconductor (CMOS) circuitry. The CMOS circuitry includes a p-channel transistor network that includes at least one p-channel transistor having a gate-induced drain leakage (GIDL) current. The IC further includes a native metal oxide semiconductor (MOS) transistor coupled to supply a bias voltage to the at least one p-channel transistor to reduce the GIDL current of the at least one p-channel transistor.
