    Abstract: PROBLEM TO BE SOLVED: To provide an efficient inductor component to facilitate integration of switched mode buck voltage regulators into system-on-chips (SOCs).SOLUTION: At least two counter wound aircoils are formed on a surface mounted device (SMD) inductor former. The aircoils are connected to three terminals on the SMD former. A single terminal is connected to a common node of both windings with two independent terminals accessing the other winding node.

    Abstract: A variable signal delaying circuit comprising an analog delay line having a control input for controlling the variable delay. A phase detector compares the input and output signals of the delaying circuit and supplies an output signal to a charge pump and integrator. A pulse stream generating arrangement produces pulse streams of different pulse widths and pulse control logic controls a selector for selecting any one of the pulse streams. In a first mode of operation, the control logic monitors the charge pump/filter output and selects the pulse stream which minimizes change in the output. The selection is fixed and the output of the charge pump/filter is then supplied as a correction signal to the control input of the analog delay line. Such an arrangement may be used to maintain minimum phase imbalance in I and Q signal paths of a quadrature frequency converter.

    Abstract: A frequency changer is provided for a radio frequency tuner. The frequency changer comprises a mixer 3 comprising a plurality of mixing stages 10a, 11a; 10b, 11b; 10c, 11c. Individual waveforms LO1, LO2 and LO3 are supplied to respective mixing stages 11a, 11b, 11c from local oscillator. The waveforms are of the same frequency but of different phases. Each mixing stage performs frequency conversion of the input frequency signal with its respective commutating signal and the frequency changed outputs of the mixing stages 11a, 11b, 11c are summed 22, 23 to form the output 21 of the mixer. The output signals of these mixing stages are supplied without relative phase shift to the summer. Improved harmonic mixing performance is achieved without degradation of the noise and intermodulation performance of the mixer.

    Abstract: A variable signal delaying circuit comprises an analog delay line (21, 23) having a control input (27) for controlling the variable delay. A phase detector (32, 34) compares the input and output signals of the delaying circuit and supplies an output signal to a charge pump and integrator (33, 35). A pulse stream generating arrangement (39-41) produces pulse streams of different pulse widths and pulse control logic (31) controls a selector (38) for selecting any one of the pulse streams. In a first mode of operation, the control logic (31) monitors the charge pump/filter output and selects the pulse stream which minimises change in the output. The selection is fixed and the output of the charge pump/filter (33, 35) is then supplied as a correction signal to the control input (27) of the analog delay line (21, 23). Such an arrangement may be used to maintain minimum phase imbalance in I and Q signal paths of a quadrature frequency converter (12-17, 21-23).
