  • Patent number: 7215162
    Abstract: A start signal outputting circuit according to the invention has a differential RF/DC convertor part 100 for converting a high frequency power (RF) into a d.c. potential (DC). The RF/DC convertor part 100 is formed by two transistors QRD, QDD working as a diode, and transistors QR1˜R3, QD1˜D3 and resistances RR1˜R3 for forming high resistances at anode sides and cathode sides of these diodes, respectively. A differential amplification part 200 disposed at a later stage of the diode has not only amplifying effect but also low-pass filtering effect together with filtering pars 120, 210 of its previous and later stages. In this case, it is designed so that current flowing through the respective circuits is about 2˜3 ?A. As a result, even if the high frequency power of the specified frequency is weak, for example ?60˜?40 dBm, a start signal outputting circuit 1000 which outputs a d.c. potential of 0.3˜2.4V, is suitable for integration and has a low power consumption can be obtained.

  • Publication number: 20060217099
    Abstract: With a capacitor C inserted in an interstage portion of multiple stages of amplifier circuits, a high pass filter is generated by the capacitor C and an input impedance |Z| of an amplifier circuit in the next stage. Accordingly, frequency components lower than a cutoff frequency fc are cut off, and therefore are not transferred to the subsequent stage. However, radio frequency components higher than or equal to a fundamental wave component determined by an envelope of a radio frequency signal intermittently transmitted can be transferred. Consequently, transfer of DC offset potentials can be cut off, and noise, such as flicker noise, having great power in a DC or near-DC zone can be effectively cut off. Thereby, the S/N ratio, detection sensitivity, and detection accuracy can be improved.

The receiver includes a frequency conversion section for reallocating the signals k in a second frequency band for sampling by a single AD converter at a sampling frequency fs such that digital data of the sampled signals k are obtained in a third frequency band extending from zero Hz to a frequency represented by fs/2; and a signal extraction section for extracting a target base band signal k from the digital data obtained by the AD conversion section. The frequency conversion section performs the reallocation in such a manner that at least a frequency represented by Jfs/2 (J is an integer) is located between the frequencies of at least two of the signals k and that the sampled signals do not overlap.

  • Publication number: 20060065722
    Abstract: A POS terminal apparatus is adapted to be connected to an external device. An application is running in the POS terminal apparatus. A device manager determines whether the external device is capable of counting a first value indicating a usage amount of the external device, and if so, the device manager acquires the first value from the external device in response to a first command from the application. A counter retains a second value indicating the usage amount of the external device and notifies the second value to the application in response to a second command from the application. If it is determined that the external device is not capable of counting the first value, the counter virtually counts the second value in accordance with a third command sent from the application to the external device. An updater updates the second value with a third value which is obtained by a fourth command from the application with reference to the first value acquired by the device manager.
