摘要： Embodiments of the invention may provide systems and methods for minimizing phase deviation and/or amplitude modulation (AM)-to-phase modulation (PM) conversion for dynamic range, radio frequency (RF) non-linear amplifiers. In order to provide high dynamic range with reduced phase error, embodiments of the invention may utilize two separate paths for processing a signal. In particular, an input signal may be sampled and divided into each path. The first signal path may be used to shape a signal, and in particular, a voltage waveform at the load. The second signal path may be used for generating negative capacitances corresponding to the voltage waveform at the load. By combining the two signals at the load, a high-dynamic range, high-frequency, non-linear amplifier can be achieved that reduces phase error resulting from amplitude fluctuations with a relatively low unity-gain frequency (fT) process.

摘要： Embodiments of the invention may be directed to a continuous analog phase shifter for radio frequency (RF) signals, which can be integrated on a CMOS process or another compatible process where inherent process-dependent passive components such as inductors and capacitors may have low quality factors. Insertion loss degradation for a given amount of phase shift may be compensated by using an active compensation circuit/device that smartly controls negative resistance generated from the compensation circuit/device to cancel out finite resistance of a network, leading to very small insertion loss variation. According to an example aspect of the invention, improved phase linearity and increased phase shift for a given size may be obtained by incorporating the compensation circuit/device. Thus, example analog phase shifters in accordance with example embodiments of the invention may have one or more of low insertion loss variation, small size, and good phase linearity over more than a 360 degree phase shift.

摘要： Embodiments of the invention may provide for reducing interference in the front-end of a communications receiver. The cancellation circuitry may be utilized in conjunction with a preliminary rejection filter for improved rejection of out-of-band interference from other radio services or circuitry. The cancellation circuit may be placed in parallel with the preliminary rejection filter and may enhance suppression at the interference frequency by matching the gain and phase of the preliminary rejection filter prior to subtracting the matched signal from the preliminary rejection filter output. The cancellation circuit need not necessary know beforehand the characteristics of the preliminary rejection filter, the interference source, or the coupling mechanism, as it may adapt to unknown or varying interferers by adapting the matching gain and phase values based on the output of the preliminary rejection filter at tap points occurring both before and after application of the cancellation signal.
