    摘要: A two phase clock generation circuit uses a current mirror and a crossbar switch to generate true and complement output clock signals that are relatively insensitive to process, voltage, and temperature variations. The current mirror generates a charging current and a discharging current that have a fixed magnitude ratio. The crossbar switch then alternately couples the charging current and the discharging current to the true and complement outputs of the clock generation circuit to generate the output clock signals. A selection signal generation unit is provided for generating the selection signal(s) required to appropriately control the switch. Because the charging and discharging currents are at fixed magnitudes and the crossbar switch is a balanced structure, the output clock signals remain aligned to a high degree of accuracy over a wide variety of conditions.

    摘要: A coupling area enhancement device includes a small coil and a large coil on opposing sides of a sheet of electromagnetic interference (EMI) absorptive material. The coupling area enhancement device may include one or more holes and may include adhesive material and sticker covers. Placement of the coupling area enhancement device may be accomplished by sticking the small coil to a host device near a contactless antenna. The large coil may also be stuck to a battery cover.

    摘要: A contactless device includes a miniaturized antenna. The antenna includes an inductive coupling element that presents a field coupling surface area to couple to a magnetic field. The inductive element may be made of layers where conductive loops are formed parallel to the layers or perpendicular to the layers. When conductive loops are formed perpendicular to the layers, the effective field coupling surface area is increased. The inductive element is positioned on an outside edge of a memory card compatible device with the field coupling surface area perpendicular to the card.
