  • Patent number: 9519300
    Abstract: Exemplary embodiment of a device is disclosed comprising a processor to provide instructions, a first voltage regulator in communication with the processor to receive provided instructions received from the processor and to dynamically modulate an output voltage based on the received instructions, and a plurality of second voltage regulators to receive the output voltage from the first regulator; the output voltage to reduce a cross-regulation interference between the second regulators due to a change in a load of at least one of the second voltage regulators.

  • Patent number: 8565669
    Abstract: An integrated circuit for achieving power reduction in a transceiver may include a jammer detector that determines an interference level corresponding to a received signal, and a transmit power detector that determines a required transmit power level for a transmitted signal. The integrated circuit may also include at least one of the following: a process monitor that determines process corners of components within the receiver and/or the transmitter, and a temperature monitor that determines a temperature of the receiver and/or the transmitter. The integrated circuit may also include a state machine. The state machine may transition the receiver from a high linearity mode to a low linearity mode if a set of operating conditions is satisfied. Similarly, the state machine may transition the transmitter from a high power mode to a low power mode if a set of operating conditions is satisfied.

  • Patent number: 7948720
    Abstract: A power controller having good transient performance and including a voltage regulator and one or more (K) transient recovery circuits is described. The voltage regulator receives a supply voltage and generates a regulator output signal used to generate K output voltages for K loads. Each transient recovery circuit detects for transients in a respective output voltage and corrects the detected transients. In one design, the transient recovery circuit compares the output voltage against a low threshold voltage, detects a low transient when the output voltage is below the low threshold voltage, and couples the output voltage to a high voltage to correct the low transient. Alternatively or additionally, the transient recovery circuit compares the output voltage against a high threshold voltage, detects a high transient when the output voltage is above the high threshold voltage, and couples the output voltage to a low voltage to correct the high transient.

  • Patent number: 7893674
    Abstract: Embodiments of the present invention are directed to switched-mode power supply (SMPS) circuits and methods thereof. The SMPS circuit receives information related to a future load change. For example, the information may be received at a decoder (e.g., a serial bus interface (SBI) decoder) from a microprocessor or microcontroller, such as a mobile station modem (MSM). The SMPS circuit may include an analog-to-digital converter configured to sample an output voltage of the SMPS circuit to determine a time when the future load change occurs. The SMPS circuit may further include a transient recovery circuit (TRC) for stabilizing the output voltage based on the received information when the future load change occurs. For example, the TRC calculates a duty cycle used to transition states of switches of the SMPS circuit to compensate for the future load change.
