摘要： A simple carrier recovery circuit capable of accurately detecting and synchronizing an incoming carrier frequency without the use of a phase locked loop (PLL) is provided. Instead of a PLL, the carrier recovery circuit includes an injection locked oscillator. The injection locked oscillator includes an input for connection to the received modulated signal. The gain of an inverter stage of a amplifier in the injection locked oscillator is modulated by the received modulated signal using an injection transistor connected between the power source and the output of the inverter stage. The gate of the injection transistor receives a signal corresponding to the received modulated signal.

摘要： A single coder/decoder shared among several multiprocessors in a digital signal processing system through time-division multiplexing between multiple processors to enhance signal processing capabilities by assigning different digital-to-analog channels to different processors for digital-to-analog conversion, while allowing all processors to operate on the same analog-to-digital data for analog-to-digital conversion, thereby resulting in chip area reduction and power consumption saving.

摘要： Upon receiving a certain type of signal in a touch screen device, deactivate a portion of the touch screen, and position the deactivated portion on a edge of the touch screen such that a user can hold the touch screen device with the thumb resting on the deactivated portion, without accidentally activating icons or active links on the touch screen. The deactivated portion can be moved, cloned, and cancelled after non-use.

摘要： An integrated circuit includes a resistor formed in a doped tub located in a semiconductor substrate. A first highly doped resistor contact region extends outward from the associated contact windows towards a second highly doped resistor contact region. The extent of the underlying tub region that lies between the highly doped tub contact regions largely determines the resistance value. The size and geometry of the highly doped resistor contact regions, and hence the resistance of the resistor, is typically determined by the same mask that defines the thin oxide regions of field effect transistors formed on the IC. In a typical application, the resistor is connected between an output buffer and a bondpad. A multiplicity of output buffers on an IC chip may each connect to corresponding bondpads using a multiplicity of the inventive resistors, which may have the same, or alternatively differing, resistance values. The resistors typically are designed to have identical external dimensions, and so layout of the resistors is facilitated for various types of IC types, including for example application specific integrated circuits (ASICs).
