  • Patent number: 7465819
    Abstract: A bisbiphenylacylphosphine oxide of formula (I) and its preparation method are provided. The formula of —Ar— is First, 10-chloro-9,10-dihydro-9-oxa-10-phosphaphenanthrene (CDOP) is prepared by using 2-phenylphenol, and then is esterified to synthesize 6-methoxy-(6H)-dibenz[c,e][1,2]oxa-phosphorin (MDOP). Next, acid chloride compounds are added for performing the Arbuzov reaction to synthesize bisbiphenylacylphosphine oxide. CDOP is hydrolyzed to be derived into 9,10-dihydro-9-oxa-10-phosphaphen-anthrene-10-oxide (DOPO), and then DOPO reacts with arylaldehyde to form secondary alcohol. Therefore, bisbiphenylacylphosphine oxide is prepared by using secondary alcohol under oxidation. Also, under a coupling reaction, DOPO reacts with the acid chloride compounds by using a Lewis acid as a catalyst to prepare bisbiphenylacylphosphine oxide.

  • Patent number: 7466177
    Abstract: A pulse-width control loop (PWCL) for clock with any pulse-width ratio within a wide range is provided. A differential programmable charge pump is employed to stabilize the current source by complementary connection. The differential programmable charge pump has a pair of differential charge pumps and a current source module to adjust the ratio of charge to discharge, so as to accelerate the range of the adjustable pulse-width ratio of the output clock and increase the output resolution. Further, a ratioless input control stage is employed to simplify the circuit design and avoid static power consumption. Moreover, the control stage adjusts rising pulse width and dropping pulse width at one period, thereby accelerating the lock speed and the range of the adjustable pulse-width ratio (i.e., duty cycle) of the input clock.
