摘要： Embodiments of methods and systems according to the application can transmit voice data by using a wireless LAN and a Bluetooth. One system embodiment can include a headset, an AP, and a terminal device to communicate with the headset according to a first protocol (e.g., Bluetooth) to transmit downlink voice data to the headset and to receive uplink voice data from the headset and to communicate with the AP according to a second protocol (e.g., wireless LAN) to transmit the uplink voice data to the AP and to receive the downlink voice data from the AP. The terminal device can receive the downlink voice data from the AP after the terminal device sends a PS-Poll frame to the AP within a period during which a transmission/reception between the terminal device and the headset is not to be performed.

摘要： An integrated circuit package includes an inductance loop formed from a connection of lead wires and one or more input/output (I/O) package pins. In one embodiment, the inductance loop is formed from a first wire which connects a first bonding pad on the integrated circuit chip to a first I/O pin of the package and a second wire which connects a second bonding pad on the chip to a second I/O pin of the package. To complete the inductor loop, the first and second I/O pins are connected by a conductive bridge between the pins. The bridge may be formed by making the I/O pins have a unitary construction. In another embodiment, the bridge is formed by a metallization layer located either on the surface of the package substrate or within this substrate. The I/O pins are preferably ones which are adjacent one another; however, the loop may be formed from non-adjacent connections of I/O pins based, for example, on loop-length requirements, space considerations, and/or other design or functional factors. By forming the inductor loop within the limits of the integrated circuit package, a substantial reduction in space requirements is realized, which, in turn, promotes miniaturization. Also, the integrated circuit may be implemented in any one of a variety of systems, at least one parameter of which is controlled by the length of the inductor loop of the package.

摘要： The present invention is directed to a linearization apparatus and method. Preferred embodiments according to the present invention can combine an auxiliary non-linear block to a functional block of a system to increase linearity of an output signal of the system such as a communication system. System overhead due to the non-linear auxiliary block can be small because of circuit structure, cost and low consumption. Further, the non-linear auxiliary block can be designed so that no feedback path is required. Further preferred embodiments can use a feedback path without loss of stability by using a cancellation apparatus or process based on an averaging detection of the output signal. For example, a feedback loop can detect power leakage in a sideband caused by non-linearities of the communication system.
