LOW-POWER RELAXATION OSCILLATOR AND RFID TAG USING THE SAME |
摘要 |
There is provided a low-power relaxation oscillator. The low-power relaxation oscillator may include: a constant current generation unit generating a current having a predetermined magnitude; a current varying unit controlling the current generated from the constant current generation unit according to a clock control signal to output the controlled current; a first controller and a second controller connected in parallel with output terminals of the current varying unit and passing or interrupting the current supplied from the current varying unit; a PMOS charging/discharging unit arranged between an output terminal of the first controller and an output terminal of the second controller; a first comparator and a second comparator connected to both ends of the PMOS charging/discharging unit, respectively, and each outputting a high or low level voltage upon receiving voltage charged in the PMOS charging/discharging unit; and a latch circuit delaying the voltages output from the first and second comparators to output oscillation signals.
