    摘要: A novel and useful RF switch that comprises four transistors configured to have four operating states, wherein at any time at most one transistor is in ‘on’ state. The switch is an on-chip switch and is constructed in using CMOS processes and technology. The switch is optionally a double pole, double throw (DPDT) switch. The switch can be used in numerous mobile devices such as a cellular phone or in the handset or base station of a cordless phone. The switch optionally selects between two antennas and between transmitter and receiver circuits. Within the switch, at least one of the at least four transistors is optionally an N-channel Metal Oxide Semiconductor (NMOS) transistor. The switch can further comprise one or more logic control circuits providing biasing voltages to one or more of the transistors. Within the switch, the control circuit comprises logic components for providing appropriate biasing voltages to the drain, source and gate terminals of the transistors in the switch.

    摘要: A dual pole dual through switch for switching between at least four states. The switch comprises four transistors such as N-channel Metal Oxide Semiconductor transistors, such that at each state at most one transistor is in “on” state, and the others are in “off” state. Each transistor has its own control circuit, which provides zero or negative voltage to the drain of the transistor, positive voltage to the source of the transistor, and control alternating voltage to the gate of the transistor. The switch can be used on-chip for devices. Such devices may include a base station or a handset of a cordless phone.

    摘要: A mobile device and method for automatically activating an application, based on the location of the mobile device.A user of the mobile device associates a location with an application or a profile to be activated at the particular location. The location can be either absolute, or relative to a second device such as a charger or a docking station. When the mobile device is connected to or in proximity to the absolute location or the second device, the current status or profile of the mobile device is stored, and the indicated application is activated.When the mobile device leaves the destination location, the application or profile stops, and the mobile device resumes its previous profile, or a default profile.

    摘要: A register file structure efficiently handles matrix and image processing. The register file contains an array of data elements and has modes for accessing of multiple data values that are aligned horizontally or vertically in a data array and for accessing data having different widths for each data value. The different modes allow manipulation of a transposed array without requiring a transpose operation and permit fast horizontal or vertical filtering with parallel access and multiplications of horizontally or vertically aligned data elements.

    摘要: A first mobile communication device that includes a first microphone, a first speaker, and a first delay unit. The first microphone is configured to (i) receive, during a conference call, a first user first microphone signal from a first user, and (ii) output a first microphone digital signal to the first delay unit. The first user first microphone signal represents audio content outputted by the first user. The first delay unit is configured to delay, by a delay period, the first microphone digital signal to provide a delayed first user first device digital signal. The first mobile communication device is configured to output, to a mixer, the delayed first user first device digital signal. The delay period is determined based on measurements executed by at least one mobile communication device out of the first mobile communication device, a second mobile communication device and a third mobile communication device.

    摘要: A low noise amplifier that includes a first cascode, a second cascode, an input circuit, an output node, a first switch, and a second switch. A source of a first common gate transistor and a drain of a first common source transistor of the first cascode are coupled to a first node of the low noise amplifier. The output node is coupled to a drain of the first common gate transistor, and to a drain of a second common gate transistor of the second cascode, thereby coupling the first cascode and the second cascode to a power supply via a load. The first switch is coupled between a gate of the first common gate transistor and the power supply. The second switch is coupled between the first node and the power supply. The first switch is configured to be open and the second switch is configured to be closed when the low noise amplifier operates at a first operational node. The first switch is configured to be closed and the second switch is configured to be open when the low noise amplifier operates at a second operational node that differs from the first operational mode by at least a gain of the low noise amplifier.
