Abstract: Several methods and systems for facilitating multimedia data encoding are disclosed. In an embodiment, a plurality of picture buffers associated with multimedia data are received in an order of capture associated with the plurality of picture buffers. Buffer information is configured for each picture buffer from among the plurality of picture buffers comprising at least one of a metadata associated with the corresponding picture buffer and one or more encoding parameters for the corresponding picture buffer. A provision of picture buffers in an order of encoding is facilitated based on the configured buffer information.

Abstract: In pipeline analog-to-digital converters (ADCs) the third harmonic can degrade the performance of the ADC, and conventional circuits that attempt to cancel this third harmonic are oftentimes sensitive to process variation, temperature variation, and common mode variations. Here a correction circuit is provided that includes a compensator that adjusts control voltages for MOS capacitors to generally ensures that the difference between the gate-source voltages and threshold voltages of MOS capacitors is generally maintained across variations of process, temperature, and common mode.

Abstract: Methods and apparatus to compensate for I/Q mismatch in quadrature receivers are disclosed. An example apparatus disclosed herein comprises a correction engine using first filter coefficients to compensate for I/Q mismatch present in a received quadrature signal; an adaptation engine to adapt second filter coefficients based on I/Q mismatch present in the received quadrature signal; and coefficient controller to occasionally adjust the first filter coefficients based on the second filter coefficients.

Abstract: An embodiment of the invention provides a method for continuously detecting when a USB client device may be charged according to a BCS charging standard. Power is supplied from a USB host device to the USB client device with a first current limit. Next, the USB host device monitors data lines D+ and D? for a first part of a handshake. When the first part of the handshake is detected, a second part of the handshake is provided by the USB host device indicating that the USB client device may be changed according to the BCS charging standard. All current sources and all voltage sources that are coupled to the data lines D+ and D? are decoupled from data lines D+ and D? after the handshake is complete. After the data lines are decoupled, communication may begin between the USB host device and the USB client device.

Abstract: A method and apparatus for linearly adjusting the bandwidth of a high-order bandpass filter. A high-order bandpass filter is formed by cascading together two or more low-order bandpass filters. The bandwidths and center frequencies of each individual low-order bandpass filter is adjusted. The center frequency of some low-order bandpass filters are adjusted so as to achieve linear adjustment of the bandwidth of the high-order bandpass filter.
