    摘要: A level shifter increase a voltage level of an output signal with relatively lower power consumption by adopting current-starved configuration. The level shifter includes an input unit and a driving unit. The input unit includes a current-starved inverter configured to generate a control signal in response to an input signal and a bias voltage. The input unit is powered by a first power supply voltage. The driving unit generates an output signal in response to the control signal. The output signal has a voltage level higher than the input signal, and the driving unit is powered by a second power supply voltage higher than the first power supply voltage.

    摘要: A signal converter capable of stabling converting input signals in an extended operation margin, a radio frequency identification (RFID) tag having the signal converter and a method of driving a RFID tag. The signal converter includes a first signal converter which converts an incoming analog signal into a power signal, a second signal converter which converts the analog signal into a first demodulation signal, a signal amplifier which amplifies the first demodulation signal to output a second demodulation signal such that a value of an externally-supplied reference signal is included in a peak-to-peak range of the second demodulation signal, and a logic signal generator which converts the second demodulation signal into a digital signal in response to the power signal. Because the second demodulation signal has an extended operation margin in converting analog signal into digital signal, stable conversion of the input signals is possible, and rate of recognizing RFID tag is improved.
