Abstract: A buffer circuit includes a first feedback buffer to receive a first component of a current-mode signal and a second feedback buffer to receive a second component of the current-mode signal. The buffer circuit also including a first inverter having a first input coupled to an output of the second feedback buffer and to an input of a first current circuit through a first filter, a first output coupled to an input of the first feedback buffer. The buffer circuit also includes a second inverter having a second input coupled to an output of the first feedback buffer and to an input of a second current circuit through a second filter, and a second output coupled to an input of the second feedback buffer.

Abstract: Wideband signal buffers that can be employed for mmWave (millimeter wave) communication are disclosed. One example signal buffer comprises a variable gain amplifier (VGA) that receives two control words and outputs a feedback signal, wherein both an amplitude and a phase of the feedback signal are based on the two control words and on a bias voltage; and a matching network comprising a first inductor that outputs the bias voltage, a second inductor, and a third inductor that receives the feedback signal from the VGA, and wherein the first, second, and third inductors are magnetically coupled to each other, wherein the signal buffer is configured to receive a RF (Radio Frequency) input and to generate a RF output from the RF input based on a transfer function of the signal buffer, wherein the transfer function is based at least in part on the feedback signal.

Abstract: When fresh water is produced from salt water or similar by evaporation of untreated or crude liquid in an evaporation device under partial vacuum and by vapor condensation in a condensation device connected with the vapor outlet of the evaporation device a high degree of evaporation and cost effectiveness can be obtained in that the evaporation device and the condensation device in a disconnected condition, are filled with crude or clean liquid, respectively, and are subsequently exposed to a partial vacuum created by volume enlargement under hermetically sealed conditions and that the evaporation device and the condensation device are not flow-connected with each other until they are under partial vacuum.

Abstract: A device for producing a purified liquid from an uncleaned liquid has at least one evaporator (10) for evaporating the supplied uncleaned liquid, and at least one condenser (23) for condensing the supplied steam, each condenser (23) being connected to the steam outlet of at least one upstream evaporator (10) by a connection pipe (47). A pressure difference is provided between the evaporator (10) and the condenser (23). In order to also generate energy, besides producing the purified liquid, at least one steam-operated working machine (70) to which the steam which can be supplied to the condenser (23) can be applied, is associated with the connection pipe (47).

Abstract: In order to perform the electrochemical roughening of the surface of preferably strip-like metal substrate for the production of printing plates or the like so that the surface is free of smuts and stripes with an even distribution of the roughness, there is a roughening station with three zones and in each zone the current density, the frequency, the temperature of the electrolyte, the type of electrolyte and the residence time may be individually set. Accordingly in the first zone it is possible to use a higher frequency and a higher current density than in the second zone in order to produce a large number of points of attack. In the second zone a longer residence time serves to enlarge the points of attack which have already been formed. In the third zone a particularly high frequency may be used to remove smuts.
