  • Advanced gain shaping for envelope tracking power amplifiers
    Patent number: 11082021
    Abstract: Envelope tracking power amplifiers with advanced gain shaping are provided. In certain implementations, a power amplifier system includes a power amplifier that amplifies a radio frequency (RF) signal and an envelope tracker that controls a voltage level of a supply voltage of the power amplifier based on an envelope of the RF signal. The power amplifier system further includes a gain shaping circuit that generates a gain shaping current that changes with the voltage level of the supply voltage from the envelope tracker. For example, the gain shaping circuit can include an analog look-up table (LUT) mapping a particular voltage level of the supply voltage to a particular current level of gain shaping current. Additionally, the gain shaping circuit biases the power amplifier based on the gain shaping current.

  • Pre-charged fast wake up low-dropout regulator
    Patent number: 11073854
    Abstract: Embodiments described herein present a new LDO design that eliminates the need for the sleep bias circuitry included in other systems. Further, the new LDO design can be biased with a small fraction of the operating current enabling the LDO to wake up substantially faster than previous LDO designs that include separate sleep circuitry. In some cases, the LDO can instantly (or faster than other LDOs) transition from a sleep mode to an operating mode enabling improved operation compared to prior LDOs. Furthermore, the new LDO design maintains a non-breakdown voltage across the transistors reducing the need to enter sleep mode to prevent transistors of the LDO from entering a breakdown region.

  • Apparatus and methods for biasing of power amplifiers
    Patent number: 11070171
    Abstract: Apparatus and methods for biasing power amplifiers are provided herein. In certain embodiments, a power amplifier includes a bipolar transistor having a base biased by a bias network having a reactance that controls an impedance at the transistor base to achieve substantially flat phase response over large dynamic power levels. For example, the bias network can have a frequency response, such as a high-pass or band-pass response, that reduces the impact of power level on phase distortion (AM/PM).
