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 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： As wireless communication technology evolves, various transceivers become integrated into a single system, which implements a seamless connection to search available frequency bands and to provide wireless connections regardless of their wireless standards. One of the key technologies for seamless implementation is an ultra-wideband local oscillator, which can overcome the restriction of limited tuning range in typical RF local oscillators. Many RF oscillators incorporate LC-tuned oscillators because of their good noise performance while their tuning range is limited by fixed inductance and varied capacitance. The planar inductor fabricated on the CMOS process occupies a large area as well. By replacing the planar inductor with the array of bondwires, and including switches to provide proper impedance for the circuit to generate negative impedance, the tuning range of a CMOS voltage-controlled oscillator (VCO) is extended more than 100%, which number can not be achieved in a convention VCO.

摘要： Embodiments of the invention may provide CMOS power amplifiers with power mode control to provide the desired power-added efficiency (PAE), idle current, output power, and Adjacent Channel Leakage Ratio (ACLR). For instance, there may be a multi-mode WCDMA CMOS RF power amplifier having high/medium/low output power modes aimed to achieve high PAE and low idle current in a portable wireless environment. According to an example embodiment, a CMOS RF power amplifier may provide a plurality of separate signal paths for purposes of supporting multi-power modes. For example, there may be a first signal path which supports a high-power mode, and a second path which is subsequently divided into two recursive signal paths or sub-paths to support respective medium and low-power modes. One of the three power modes may be selected or controlled using bias control switches in the first and second paths.
