摘要： A dB-linear voltage-to-current (V/I) converter that is amenable to implementation in CMOS technology. In a representative embodiment, the dB-linear V/I converter has a voltage scaler, a current multiplier, and an exponential current converter serially connected to one another. The voltage scaler supplies an input current to the current multiplier based on an input voltage. The current multiplier multiplies the input current and a current proportional to absolute temperature and supplies the resulting current to the exponential current converter. The exponential current converter has a differential MOSFET pair operating in a sub-threshold mode and generating an output current that is proportional to a temperature-independent, exponential function of the input voltage.

摘要： Fractional frequency division is performed by sequentially selecting phase signals for division, where transitioning from a previous phase signal to a next phase signal for division occurs in response to not only the frequency-divided previous phase signal but also a second one of the phase signals. A phase transition that is triggered at least in part in response to a second phase signal having a phase that is greater (with respect to the phase signal sequence) than the phase of the next phase signal can aid minimization of signal glitches. The first frequency-divided signal can be further divided to produce a second frequency-divided signal having a 50-percent duty cycle.
