This result is quite consistent with the knee frequency
(fknee) approach given ,
The lower the knee frequency in the frequency-domain, the longer the rise time of the signal in the time-domain.
This pushes the knee frequency of the signal's spectrum to lower frequency, and increases the rise time of the signal.
With a flat response, the spectrum of the transmitter is preserved at the receiver; the knee frequency is the same as the transmitter; the rise time is the same, no additional ISI and no additional collapse of the eye.
The knee frequency is the frequency at which the value of 1/f noise and white noise contributions are equal.
This can be achieved "if the post detection knee frequency [f.
By comparison, specifying in the DC section cannot be used to predict performance in the main operating region because the knee frequency ([f.
One limitation in pursuing direct modulation architectures for future wide-bandwidth-generating designs is the low knee frequency exhibited by devices that target this approach.
L] = 2[pi]fL provides the expression for inductive reactance, but here f is the knee frequency
which is defined as 0.
gs]) The knee frequency
is a function of gate resistance and gate periphery.
We also need to do additional calculations such as Dk and Df on the signal's knee frequency (this can be done in an Excel calculator) and the CAD_width and CAD_separation from the field-solver results.
Both strongly change over the frequency, so derive their values on the signal's knee frequency.
