Abstract: A digital adaptive predistorter look up table (DAPD-LUT) technique dynamically adapts a look up table (LUT) an LUT spacing for linearizing a power amplifier (PA). It optimizes the LUT spacing for the PA without prior knowledge of system state information. A size-N LUT divides a whole unsaturated PA input amplitude range into N bins, each predistorted by an entry of the LUT. The LUT is indexed by an input amplitude of a modulated signal via an index mapper to implement an unconditionally non-uniform LUT spacing. A spacing adaptor online interactively adapts the LUT spacing. The adapted LUT spacing balances the inter-modulation distortion (IMD) power at the PA output corresponding to each bin, so that the total IMD power at the PA output is minimized. This dynamically-optimum technique is practical, robust, and with low complexity.

Abstract: Read the description file of a PCBA without determining and selecting connectors which might be relevant to boundary scan. The description file of the PCBA determines which pins of the connectors on the PCBA should correspond to the pins of a test I/O module. And use the wiring report generated by an auto test program generator to correspond the pins of the test I/O module to the pins of the connectors which are accessed by boundary scan. Thus the IC of the test I/O module would not have any unused pin between any two consecutive pins wired to the connectors of the PCBA.

Abstract: An echo cancellation circuit for an RFID reader and the method thereof are provided. The echo cancellation circuit includes a gain calculator, a gain adjustment circuit, and a subtraction circuit. The gain calculator provides a complex gain value according to a carrier signal and a received signal through an adaptive algorithm. The gain adjustment circuit is coupled to the gain calculator. The gain adjustment circuit multiplies the carrier signal by the complex gain value, and outputs the result of the multiplication. The subtraction circuit is coupled to the gain adjustment circuit. The subtraction circuit subtracts the output of the gain adjustment circuit from the received signal, and then provides the result of the subtraction as the output signal of the echo cancellation circuit.

Abstract: The present invention provides a method of fabricating a flash memory cell without silicide formation on the source regions. A liquid deposition oxide layer is formed selectively only on a common source region by using a mask layer. The liquid deposition oxide layer is formed on the common source region in order to cover the common source region. Therefore, once a salicide step is performed, a silicide layer will not form on the common source region.

Abstract: The method plans a predetermined circuit pattern on an inner surface of a constructive object and plans a contact portion on an outer surface of the constructive object for external electric connection. Laser is used to scan an area in which both the circuit pattern and the contact portion are located. A through hole is formed to make both the circuit pattern and the contact portion uninsulated and to form an irregular roughened surface on the area scanned by heat of the laser. A layer of conductive material is deposited on the roughened surface by a mixture of a catalyst solution and metal powder. The constructive object is immersed in a reaction tank to implement electroless plating to gradually thicken the layer of conductive material to become a conductor. The conductor penetrating the through hole makes the circuit pattern and the contact portion electrically connected.
