摘要： An RFID tag is integrated with a processor of an electronic product for anti-theft purpose. The RFID tag receives an enable mark when the electronic product is checked out at a point of sale. Only when the processor receives the enable mark from the RFID tag can the start-up sequence of the electronic product be executed. An RFID tag is integrated with a sensor of an electronic product for data transmission purpose. Data measured by the sensor can be stored in the memory of the RFID tag and outputted via the antenna of the RFID tag.

摘要： According to one embodiment of the invention, an amplifier includes a gate bias circuit operable to generate a gate bias voltage and a common gate amplifier that includes a transistor having a gate biased by an output of the gate bias circuit and also having a source connected to an inductor for providing a path to ground for direct current flowing through the transistor. According to another embodiment of the invention, a method for amplifying a signal by an amplifier includes generating a gate bias voltage indicative of a difference between a reference voltage and an output voltage of the amplifier, biasing the gate of the common-gate amplifier with the gate bias voltage, and blocking, by a passive device, alternating current signals from flowing from the source of the transistor to ground.

摘要： The mixer circuit includes a differential rf input driver; a differential local oscillator input circuit coupled to the differential rf input driver; a non-linear load coupled to the differential local oscillator input circuit wherein the non-linear load compensates for non-linearity of the differential rf input driver. The non-linear load has a V-I (voltage-current) transfer function the inverse of the input driver. This improves the mixer linearity without sacrificing the Gain or Noise Figure.

摘要： A PHY entity for a UWB system utilizes the unlicensed 3.1-10.6 GHZ UWB band, as regulated in the United States by the Code of Federal Regulation, Title 47, Section 15. The UWB system provides a wireless pico area network (PAN) with data payload communication capabilities of 55, 80, 110, 160, 200, 320 and 480 Mb/s. The UWB system employs orthogonal frequency division multiplexing (OFDM) and uses a total of 122 sub-carriers that are modulated using quadrature phase shift keying (QPSK). Forward error correction coding (convolutional coding) is used with a coding rate of 11/32, 1/2, 5/8 and 3/4.

摘要： A programmable gain amplifier includes an operational amplifier coupled thereto a plurality of resistors to perform a feedback control, thereby rendering a closed-loop gain A f ⁡ ( s ) = A ⁡ ( s ) 1 + A ⁡ ( s ) · β , where β is a feedback factor determined by the resistance of the resistors and A(s) is an open-loop gain of the operational amplifier. The operational amplifier includes a first-stage amplifying circuit, a second-stage amplifying circuit, and a compensating capacitor coupled to an output end of the first-stage amplifying circuit and having an equivalent capacitance variable to adjust a dominant-pole frequency of the open-loop gain of the operational amplifier.
