Nettet28. aug. 2013 · Because we are not interested in investigating any specific chiral liquid crystal, we express our quantities of interest in terms of “reduced” ( i.e ., dimensionless) units. For example, length is given in units of σ, energy in units of ɛff, temperature in units of ɛff/kB and pressure in units of ɛff/σ3.

NettetThe high performance PLL with figure of merit of –236 dBc/Hz and high phase detector frequency can attain very low in-band noise and integrated jitter. The high-speed N-divider has no pre-divider, thus significantly reducing the amplitude and number of spurs. There is also a programmable input multiplier to mitigate integer boundary spurs.
