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 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.

摘要： A system and method for testing digital to analog converters (DAC) in a serial interface having a comparator to receive an input signal and a local offset signal is disclosed. A first DAC selectably provides one of a global offset to the input signal during a normal mode of operation and a first test signal to the comparator during a test mode of operation. A second DAC selectably provides one of the local offset signals to the comparator during the normal mode of operation and a second test signal to the comparator during the test mode of operation. A test module may cause the first DAC to determine a first test signal to provide to the local offset input of the comparator and may cause the second DAC to incrementally change a test signal provided to the comparator.

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.
