    摘要： A phase detector 10 is disclosed herein. A clock signal CLK (OR I), a marker signal MARK (or Q) and a data signal D are provided. The data signal may comprise a periodic clock signal. Sampler circuitry 50 receives the clock signal CLK, the marker signal MARK and the data signal D and generates a sampled clock signal and a sampled marker signal. Sign modifier circuitry 52 then receives the sampled clock signal and sampled marker signal and generates first and second command signals. Select circuitry 54 receiving these command signals selects a valid command signal based upon the data signal.

    摘要： A method and apparatus for reducing aperture uncertainty and kick-back noise in high speed comparators is disclosed. The disclosed method is used in a comparator for comparing a first signal (INP) and a second signal (INM) and having a track mode and a regenerative mode of operation. The steps of this method are as follows. A first input current representing the first signal is switched through a first output node (OUTP) during the track mode and a second input current representing the second signal is switched through a second output node (OUTM) during the track mode. During the regenerative mode, approximately half of the first input current is switched through the first output node (OUTP) and approximately half of the first input current is switched through the second output node (OUTM). Also during the regenerative mode, approximately half of the second input current is switched through the first output node and approximately half of the second input current is switched through the second output node.

    摘要： The invention provides a water/oil/water duplex emulsion in which the external continuous phase is gelled. This gelling is obtained by having an osmotic pressure component, e.g. an electrolyte, in the internal aqueous phase which draws water from the external phase through the oil phase. The structure is firm but contains a considerable volume of available aqueous phase. The structure is of value in e.g. foods and cosmetics.
