摘要： A radio frequency identification reader and a radio frequency identification tag that use an ultrahigh frequency band, and action methods of the radio frequency identification reader and the radio frequency identification tag. The radio frequency identification reader includes: a data generator generating data to be transmitted to a radio frequency identification tag; if a command to control the radio frequency identification tag has to be authenticated, a reader controller controlling the data generator to generate the data including an authentication code; and a reader transmitter transmitting the data to the radio frequency identification tag. As a result, securing of communications of a specific command between the radio frequency identification reader and the radio frequency identification tag can be reinforced.

摘要： An ultra low power oscillator includes a current supply unit converting current supplied from an external bias power source into first and second low currents of predetermined amounts, and an oscillation unit oscillating and creating a predetermined frequency signal if the first and second low currents are supplied from the current supply unit. The oscillation unit includes a plurality of inverters connected in series, and the current supply unit includes a current limit circuit composed of NMOS and PMOS transistors connected to the respective inverters. The current flowing when the transistors in the respective inverters are simultaneously turned on is limited, and thus the power consumption can be reduced.

摘要： A voltage transform circuit transforms a transferred voltage to a desired magnitude of voltage. The voltage transform circuit includes: a first power supply unit for providing a digital voltage (Vdd-1) of a first magnitude; a second power supply unit for providing an analog voltage (Vaa-2) of a second magnitude; and a voltage transform unit formed with a plurality of MOS transistors, wherein the MOS transistors operate to transfer the digital voltage (Vdd-1) from the first power supply unit, and output a digital voltage (Vdd-3) of a third magnitude corresponding to the analog voltage (Vaa-2) transferred from the second power supply unit. By using an analog voltage (Vaa-2) that is higher than the digital voltage (Vdd-1), it becomes possible to increase the magnitude of the output digital voltage (Vdd-3). By supplying this high digital voltage (Vdd-3) to a charge pump, the level of the charge pump is lowered.
