  • Patent number: 6924704
    Abstract: When both the sourcing command and the sinking command to the phase comparator are high, the charge pump phase detector creates a high impedance output dead period, which is undesirable. The dead zone can be minimized by resetting the phase comparator when both sourcing command and sinking command are high. Accurate timing of the reset signal is crucial to good PLL phase noise performance and also to the elimination of the dead zone problem. In our invention, accurate reset timing is achieved by including the charge pump delay time caused by the input gate capacitance of the output complementary MOSFETs in the reset signal path.

  • Patent number: 6149461
    Abstract: A solderless coaxial cable termination mounting device comprises a housing having a top and a bottom and an axially extending opening extending therethrough. A first eyelet is coaxially positioned in the opening adjacent the top of the housing. A second eyelet coaxially is positioned in the opening adjacent the bottom of the housing. The housing further defines a radially extending channel for receiving a coaxial cable. The coaxial cable has an internal wire which is in communication with the first eyelet and an external wire which is in communication with the second eyelet.
