摘要： A noise reduction circuit useful as a clock restoration circuit includes a DC removal circuit (67) for removing a DC level from an input pulse train. An integrator (54) integrates the input pulse train after a DC level has been removed and a comparator (59) compares the integrator output with a threshold value (Vmp) to detect for a missing pulse. A pulse generator (65) inserts into the input pulse train an additional pulse delayed with respect to any missing pulse and an output pulse train having reduced noise is derived from the integrator output. In another noise reduction circuit blanking pulses B* are generated and are used to cancel additional spurious pulses in the input pulse train. A phase noise reduction circuit producing a pulse train having a predetermined phase relationship and/or duty cycle relative to an input signal or a clock signal is also described. Also described is the application of such circuits to a fractional rate multiplier circuit and a fractional-N phase-locked loop synthesiser.

摘要： A slope generator (100) generates, in response to an input signal (V_in), a slope between a first (V_l) and a second (V_h) voltage level of an output voltage (V_out) at an output node (25). The slope generator (100) comprises a capacitor (C_ramp) coupled to the output node (25), a first current source (20) for providing a first current (I_up) to the output node (25), and a second current source (30) for providing a second current (I_dn) to the output node (25) controlled by a first current switch (40). A control electrode of a first current path of the first current switch (40) is coupled to and controlled by the input signal (V_in), a second current path is coupled to the output node (25), and the first current switch (40) provides the first (V_l) and the second (V_h) voltage levels, or corresponding voltage levels derived therefrom, to the output node (25).

摘要： Sawtooth oscillator comprising: a first capacitor (14), a current source (12) having an output (10) coupled to the first capacitor (14) for supplying a charge current (I) to the first capacitor (14), discharging means (20, 22) for discharging the first capacitor (14) during a discharge period (TDS) in response to a voltage (UC) on the first capacitor (14), a second capacitor (30) coupled to the output (10) of the current source (12), interrupting means (26) for interrupting the supply of the charge current (I) to the first capacitor (14) during an interrupt period (TIS) part of which charge current occurring during the discharge period (TDS), supply means (24, 26, 40, 46, 34) for supplying subsequent to the interrupt period (TIS) the first capacitor (14) with a charge surplus built up by the charge current (I) in the second capacitor (30). The current supply to the first capacitor (14) is temporarily interrupted by the interrupting means (48) at least during part of the discharge period. The second capacitor (30) operates as an auxiliary capacitor in which the charge is stored which would otherwise have been supplied to the first capacitor (14). After the interrupt period the charge stored in the second capacitor (30) is supplied back to the first capacitor (14) by the supply means (50). In this manner there is achieved that substantially no charge current is lost during a total period of time of a charge and discharge cycle. In the total period of time the whole charge current of the current source ends up in the first capacitor, so that tolerances in the discharge period no longer affect the oscillation frequency of the sawtooth oscillator.

摘要： A method and apparatus for triggering and measuring electrochemiluminescent phenomena using a voltage waveform applied at the voltammetric working electrode which improves the precision and accuracy of measurements. This waveform has a decreasing scan rate in the range of voltages for which electrochemiluminescence is triggered and is substantially sinusoidal in shape in this range. The waveform results from locating the reference electrode (20) of a potentiostat in close potential proximity to its counter electrode (16), and applying a uniform scanning voltage waveform at the reference electrode (20). The waveform also can be synthesized digitally, converted to analog form, and applied directly to the working electrode (18) with the reference electrode (20) in close potential proximity to the working electrode (18).
