  • Publication number: 20190036493
    Abstract: Aspects disclosed in the detailed description include an envelope tracking (ET) amplifier circuit. The ET amplifier circuit includes ET tracker circuitry configured to provide an ET modulated voltage, which tracks an ET modulated target voltage, to an amplifier circuit(s) for amplifying a radio frequency (RF) signal. The ET amplifier circuit also includes fast switcher circuitry that is activated to provide an alternate current (AC) current to the amplifier circuit(s) when the RF signal includes a higher number of resource blocks (RBs). However, the fast switcher circuitry and its associated control circuitry may incur a processing delay that can cause the fast switcher circuitry to lag behind the ET modulated target voltage. As such, the ET amplifier circuit further includes timing adjustment circuitry to help compensate for the processing delay, thus helping to maintain efficiency of the ET tracker circuitry for improved performance of the ET amplifier circuit.

  • Patent number: 10193502
    Abstract: A dual-mode envelope tracking (ET) power management circuit is provided. An ET amplifier(s) in the dual-mode ET power management circuit is capable of supporting normal-power user equipment (NPUE) mode and high-power user equipment (HPUE) mode. In the NPUE mode, the ET amplifier(s) amplifies a radio frequency (RF) signal(s) to an NPUE voltage based on a supply voltage for transmission in an NPUE output power. In the HPUE mode, the ET amplifier(s) amplifies the RF signal(s) to an HPUE voltage higher than the NPUE voltage based on a boosted supply voltage higher than the supply voltage for transmission in an HPUE output power higher than the NPUE output power. The ET amplifier(s) maintains a constant load line between the NPUE mode and the HPUE mode. By maintaining the constant load line, it is possible to maintain efficiency of the ET amplifier(s) in both the NPUE mode and the HPUE mode.

  • Patent number: 10090762
    Abstract: A direct current (DC) voltage converter configured to transition between operation modes is disclosed. A voltage selection circuitry is provided in a DC voltage conversion circuit to control a buck-boost converter that generates a DC output voltage. As opposed to conventional methods of switching the buck-boost converter between a buck mode and a boost mode based on a single switching threshold, the voltage selection circuitry is configured to switch the buck-boost converter between the buck mode and the boost mode based on multiple voltage thresholds. Each of the multiple voltage thresholds defines a respective range for the DC output voltage. By controlling the buck-boost converter based on multiple voltage thresholds, it is possible to provide a smoother transition between the buck mode and the boost mode, thus reducing voltage errors in the DC output voltage and improving reliability of the DC voltage conversion circuit.

  • Patent number: 9225231
    Abstract: A direct current (DC)-DC converter, which includes an open loop ripple cancellation circuit, a switching supply, and a parallel amplifier, is disclosed. During a calibration mode, the parallel amplifier provides a parallel amplifier output current to regulate a power supply output voltage based on a calibration setpoint. The switching supply drives the parallel amplifier output current toward zero using a switching control signal, such that during the calibration mode, an estimate of a current gain is based on the switching control signal. Further, during the calibration mode, the open loop ripple cancellation circuit is disabled. During a normal operation mode, the open loop ripple cancellation circuit provides a ripple cancellation current, which is based on the estimate of the current gain.

  • Patent number: 9159516
    Abstract: The present disclosure provides a system and method for controlling positioning of a movable member of a MEMS microactuator to reduce bouncing and ringing. The system includes control circuitry in communication with the MEMS microactuator. The control circuitry is adapted to linearly increase an actuation signal from a first state to a second state to urge the movable member from a first position to a second position and hold the movable member in the second position. The control circuitry is further adapted to linearly decrease the actuation signal from the second state to the first state to release the movable member to the first position. A transition time is not less than the inverse of one quarter of a natural frequency of the movable member as the movable member moves to the first position.
