  • Publication number: 20160036389
    Abstract: A low frequency loss correction circuit that improves the efficiency of a power amplifier at near-DC low frequencies The low frequency loss correction circuit can include a signal error detection circuit configured to produce an error signal in response to detecting one or more frequency components of a tracking signal below a cutoff frequency that are substantially attenuated through a capacitive path. The low frequency loss correction circuit can include a drive circuit configured to convert the error signal into a low frequency correction signal, and provide the low frequency correction signal to a voltage supply line, the low frequency correction signal including at least some of the one or more frequency components of the tracking signal below a cutoff frequency that are substantially attenuated through the capacitive path.

  • Publication number: 20150349809
    Abstract: Implementations of radio frequency switch controllers within the scope of the appended claims are configured to reduce the impact of the clock signal induced spurs. In particular, implementations of switch controllers described herein include a poly-phase clocking scheme, as opposed to a single phase to clock the charge pump stages of an negative voltage generator. In some implementations poly-phase clocking schemes reduce the clock signal induced spurs and may preclude the need for additional on-chip or off-chip decoupling capacitors that add to the cost and physical size of a complete front end module solution.

  • Patent number: 9197128
    Abstract: Apparatus and methods for voltage converter bypass circuits are provided. In one embodiment, a voltage conversion system includes a bypass circuit and a voltage converter including an inductor and a plurality of switches configured to control a current through the inductor. The bypass circuit includes a first p-type field effect transistor, a second p-type field effect transistor, a first n-type field effect transistor, and a second n-type field effect transistor. The first and second n-type field effect transistors are electrically in series between a first end and a second end of the inductor. Additionally, the first and second p-type field effect transistor transistors are electrically connected in series between the first end and the second end of the inductor.

  • Publication number: 20120077551
    Abstract: Circuits and methodologies related to high-voltage tolerant regulators are disclosed. In some implementations, a voltage regulator can be configured to be capable of being in a regulating state and a bypass state. In the regulating state, an input voltage greater than a selected value can be regulated so as to yield a desired output voltage such as a substantially constant voltage. In the bypass state, an input voltage at or less than the selected value can be regulated so as to yield an output voltage that substantially tracks the input voltage. Such a capability of switching between two modes can provide advantageous features such as reducing the likelihood of damage in a powered circuit due to high input voltage, and extending the operating duration of a power source such as a rechargeable battery. Also disclosed are examples of how the foregoing features can be implemented in different products and methods of operation and fabrication.
