摘要： A gain calibration circuit for a radio frequency mixer in a wireless transceiver includes a reference signal generator that generates a reference signal. A comparator receives the reference signal and a second signal that is proportional to current flowing through the transmitter mixer and generates a difference signal. An adjustment circuit adjusts a transconductance gain of the mixer based on the difference signal. The adjustment circuit includes a plurality of binary weighted transconductance cells. The transconductance gain is calibrated during idle time between data packets or after power on, hardware reset, or software reset.

摘要： A network device comprises a host, including a device driver, and a network interface. The network interface includes a first media access controller, the first media access controller configured to, when activated, use a media access controller address for transferring data from the host to the first network, and transferring data from the first network to the host. A second media access controller is configured to, when activated, also use the media access controller address for transferring data from the host to the second network, and transferring data from the second network to the host. The device driver is configured to select either the first network or the second network for communication with the host, and the first media access controller or the second media access controller is respectively activated in response to the device driver selecting the first network or the second network.

摘要： Different scan modes are provided for Bluetooth devices. In at least some embodiments, a narrowband scanning mode looks for signal energy on individual transmission frequencies at a time. By looking for signal energy rather than decoding transmitted packets, at least some of the components in a Bluetooth device can remain in an idle or rest state. A midband scanning mode looks for signal energy across multiple different frequencies at a time. Again, by looking for signal energy across multiple different frequencies rather than decoding transmitted packets, at least some of the components in a Bluetooth device can remain in an idle or rest state. A wideband scanning mode looks for signal energies across all relevant frequencies at a time. At least some embodiments enable a Bluetooth device to switch between scanning modes.

摘要： The present system and method manage a rechargeable battery comprising two or more battery cells or series stacks of cells. The system includes a set of switches, each of which connects a cell or stack of cells between positive and negative nodes when actuated, or connects one cell in a stack of cells to another cell in the stack when actuated, such that when all the switches in a given stack are actuated, it is connected between the positive and negative nodes. An electrical load is directly connected to the positive and negative nodes. A controller determines the state of each cell or stack of cells by measuring and/or calculating one or more predetermined characteristics, and selectively actuates the switches based on the states of the cells or stacks of cells so as to enhance the life of the battery.
