    摘要: A method, a computer program product, and an apparatus are provided. The apparatus determines an availability of a wireless wide area network (WWAN) subframe, and utilizes the WWAN subframe for peer-to-peer communication when the WWAN subframe is available. Accordingly, peer mobile terminals or devices may establish direct peer-to-peer links for communicating small amounts of information without affecting the quality of existing WWAN communications. In the wireless wide area network (WWAN) scenario, communication between mobile terminals is facilitated through uplink/downlink channels between the mobile terminals and a base station (i.e., WWAN link). Therefore, for various types of applications, an efficient means of communicating a small amount of information frequently is provided that does not require large amounts of signaling overhead.

    摘要: Disclosed are CMOS-based devices for switching radio frequency (RF) signals and methods for biasing such devices. In certain RF devices such as mobile phones, providing different amplification modes can yield performance advantages. For example, a capability to transmit at low and high power modes typically results in an extended battery life, since the high power mode can be activated only when needed. Switching between such amplification modes can be facilitated by one or more switches formed in an integrated circuit and configured to route RF signal to different amplification paths. In certain embodiments, such RF switches can be formed as CMOS devices, and can be based on triple-well structures. In certain embodiments, an isolated well of such a triple-well structure can be provided with different bias voltages for on and off states of the switch to yield desired performance features during switching of amplification modes.

    摘要: A scalable and ultrasensitive frequency-shift magnetic array scheme. The theoretical limit of the sensor noise floor is shown to be dominated by the phase noise of the sensing oscillators. To increase the sensitivity, a noise suppression technique, Correlated Double Counting (CDC), is described with no power overhead. As an implementation example, a 64-cell sensor array is designed in a standard 65 nm CMOS process. The CDC scheme achieves an additional 6 dB noise suppression. The magnetic sensing capability of the presented sensor is verified by detecting micron size magnetic particles with an SNR of 14.6 dB for a single bead and an effective dynamic range of at least 74.5 dB. Applications in biosensing are contemplated, among other possible uses. Measurement of electrical properties is also contemplated.
