Abstract: An integrated circuit assembly includes a voltage level generator, a level shifter, a bandgap reference generator and a voltage regulator. The voltage level generator generates output voltage level signals in response to a supply voltage. The level shifter receives the output voltage level signals from the voltage level generator and generates first and second sets of control signals. The bandgap reference generator receives a reference voltage input and generates a bandgap reference signal. The voltage regulator receives a supply voltage, the bandgap reference signal the first and second sets of control signals from the level shifter and generates a constant output voltage under varying circuit conditions.

Abstract: A low power charge pump is provided that has complementary transistors capable of isolating switching noise from the input switching transistors. The charge pump uses charged currents that are matched in both magnitude and time to reduce switching noise in the output of the charge pump. The charge pump is also designed for use in a phase lock loop.

Abstract: A method and apparatus for dubbing a recording tape in a video recording and reproducing device. A source video recording and reproducing device reproduces data of a source recording tape in response to a dubbing demand from a user and confirms an error recording portion and a data unrecorded portion. The source video recording and reproducing device performs error correction with respect to the error recording portion and generates a non-recording control pulse with respect to the data unrecorded portion. The reproduced data and the non-recording control pulse is transmitted to a target video recording and reproducing device. The target video recording and reproducing device records, in a target recording tape, the reproduced data except data transmitted during an interval of the non-recording control pulse.

Abstract: A method of manufacturing a transformer that includes forming a disc-wound coil using a plurality of pre-formed cooling ducts. Each cooling duct may be supported by a support pipe secured between walls of the cooling duct, or by a removable insert. First and second conductor layers are formed, each of which include plurality of disc windings arranged in an axial direction of the disc-wound coil. A spacer layer is formed between the first and second conductor layers to form a plurality of axially-extending passages. The cooling ducts are slid into the axially-extending passages so as to be disposed between the first and second conductor layers.

Abstract: According to one exemplary embodiment, a frequency synthesizer module includes a loop filter, where the loop filter includes a capacitor having a first terminal and a second terminal. The frequency synthesizer module further includes a loop filter calibration module coupled to the capacitor in the loop filter. The loop filter calibration module causes an initial capacitance between the first terminal and the second terminal of the capacitor to increase to a target capacitance when the loop filter is in a calibration mode. The target capacitance can causes in increase in control of a bandwidth of the loop filter and a reduction in percent error of a unity gain bandwidth of the loop filter. The loop filter further includes a switched capacitor array configured to cause the initial capacitance to increase to the target capacitance in response to a digital feedback signal provided by the loop filter calibration module.
