摘要： A method is provided for operating a transmitter integrated in a microelectronic element. In a calibration phase, a plurality of operational parameters are stored for controlling a frequency response of the transmitter under each of a plurality of corresponding operating conditions. Upon detecting an operating condition such as a temperature or power supply voltage level, the corresponding stored operational parameter is applied to the transmitter to control the frequency response.

摘要： A signal detector and method to detect the presence or absence of an incoming differential signal. The method nullifies the DC off-set of the signal detector so that it can detect a signal within a very narrow window. The common mode levels of the signal and reference paths are used for calibration which is done automatically by use of an embedded algorithm residing in a digital block. The calibration range and resolution are predetermined to cope with the technology, modeling, design methodology and human error.

摘要： A design structure including a CMOS rail-to-rail differential latch is provided in which a plurality of cross-coupled devices pull first and second nodes of the latch to opposite rail-to-rail voltages. Desirably, first and second output isolating elements have inputs coupled to the first and second nodes, the output isolating elements being operable to output versions of the opposite rail-to-rail voltages as a true and a complementary output of the latch. In this way, the true output has a rising edge occurring simultaneously with a falling edge of the complementary output. The complementary output has a rising edge occurring simultaneously with a falling edge of the true output. First and second input isolating elements of the latch have outputs coupled to the first and second nodes, the first and second input isolating elements being operable to apply versions of input signals to the first and second nodes.

摘要： A voltage controlled oscillator (VCO) is provided which includes a threshold level setting circuit operable to set a lower variable threshold level and to set an upper variable threshold level. The VCO includes a frequency band selection unit operable to adjust a frequency band setting of the VCO to one of a plurality of frequency band settings. The VCO further includes a comparator operable to determine whether a control voltage of the VCO falls between the lower threshold level and the upper threshold level. The VCO further includes a threshold adjustment and calibration circuit operable to maintain the frequency band setting when the control voltage falls between the lower and upper threshold levels. Otherwise, when the control voltage lies below the lower threshold level, the lower threshold level is adjusted downward and the upper threshold level is adjusted upward, and when the control voltage lies above the upper threshold level, the frequency band selection is increased to a next higher frequency band.
