摘要： Example embodiments are directed to an apparatus and method for measuring a pulse width. A side-band signal generator may be configured to receive a given data pattern and output a side-band signal by modulating a pulse width of the received data pattern in a test mode. A phase detector may be configured to receive the side-band signal and a reference clock signal, and output a pulse signal corresponding to a phase difference between the received side-band signal and the reference clock signal. A charge pump may be configured to receive the pulse signal and output an output voltage by increasing or decreasing the output voltage based on the pulse signal. A pulse width measurer may be configured to receive the output voltage of the charge pump and determine whether pulses forming the side-band signal have appropriate widths based on whether the output voltage is included in a desired reference voltage range.

摘要： A temperature sensing circuit includes first, second and third proportional to absolute temperature (PTAT) units, and first and second subtracters. The first PTAT unit generates a first output voltage based on a reference current and a current of N times the reference current, where N is an emitter current density ratio. The second PTAT unit generates a second output voltage based on a current of twice the reference current and a current of 2N times the reference current. The third PTAT unit generates a third output voltage based on the reference current and a current of N times the reference current. The first subtracter performs subtraction on the second output voltage and the third output voltage, and the second subtracter performs subtraction on an output voltage of the first subtracter and the first output voltage.
