Publication number: 20050040791Abstract: A circuit is provided for controlling a battery-charger device with a closed-loop architecture. The circuit includes sensing means for sensing an operative quantity of the device, control means, and driving means. The control means alternately controls the sensing means to track the operative quantity during a tracking phase and to hold the operative quantity during a holding phase. The driving means provides a regulation signal that regulates the operative quantity based on a comparison between the operative quantity sensed by the sensing means and a reference value. The control means causes the driving means to hold the regulation signal during at least part of each of the holding phases. Also provided is a method of controlling a battery-charger device with a closed-loop architecture.Type: ApplicationFiled: June 16, 2004Publication date: February 24, 2005Applicants: STMICROELECTRONICS S.r.l., STMICROELECTRONICS S.A., STMICROELECTRONICS GmbHInventors: David Chesnau, Giacomo Mercadante, Patrizia Milazzo, Christopher Bernard

Patent number: 6473662Abstract: A method of signal compression of a signal to reduce the large dynamic range, for example, of the output signal of a CD player in such a way that soft passages of a piece of music are reproduced in somewhat louder manner and very loud passages of a piece of music some are reproduced in somewhat less loud manner. The signal compression circuit used therefor can be integrated completely. The audio signal is fed over a volume control, which can be adjusted by the user, and to this end, a digital setting signal in accordance with the adjustment made on the user side, is supplied via a bus line. When the audio signal is strongly increasing, a tracking signal is formed of said signal, with the amplitude thereof being dependent on the medium amplitude of the audio signal. A window comparator compares the tracking signal with a reference value, as a consequence of which the contents of the up/down counter are reduced. This reduced value is added via an adder to the digital setting signal for the volume control.Type: GrantFiled: June 11, 1999Date of Patent: October 29, 2002Assignee: STMicroelectronics GmbHInventors: Jürgen Lübbe, Johann Henkel, Peter Kirchlechner
