摘要： An output-impedance in a power amplifier is provided. A first transistor QBUF of a buffer stage is connected to a first side of a resistor RF and a second transistor QAMP to a second opposite side of the resistor RF. The first transistor feeds a current IRF to the second resistor QAMP. The current IRF at the second transistor is copied and multiplied by a factor (n) to form an output current IOUT, as (1+n)* IRF. The current IRF is fed back to the first transistor and the output current IOUT is fed to a load resistor R.

摘要： The invention relates to a method for dewatering particle collections with the aid of a filter press in a cyclic sequence comprising filling, dewatering and emptying stages. The various stages within each cycle and between consecutive cycles are followed-up and determined by measuring continuously a magnitude which varies with the mass of the press and its contents, preferably the pressure exerted by the press and its contents on the surface supporting the press.
