    Abstract: A method and an arrangement for processing a received signal which comprises phase-shift modulated or amplitude-quadrature modulated part-signals which are transmitted in a plurality of different frequency bands, wherein the received signal is processed in a plurality of stages in succession, by multiplying all the input signals to each of the stages by two mutually orthogonal signals in each case to form two intermediate signals in each case, wherein the intermediate signals from one stage in each case act as the input signals to whichever is the succeeding stage in the particular case and the received signal acts as the input signal to the first stage, and wherein an in-phase and/or an quadrature component of the individual part-signals in the different frequency bands are determined from the intermediate signals from the last stage. Parallel, simultaneous reception of a plurality of frequency bands can be implemented relatively easily in this way.

    Abstract: A traveling wave amplifier comprises a first normally off MOS transistor having a drain, source and gate terminal. The drain terminal is connected to a node of a drain line, which is connected to a first supply voltage potential via a connecting resistor. The gate terminal is connected to a node of a gate line, onto which an input signal is coupled. The source terminal is coupled to a second supply voltage potential via a first resistor. The traveling wave amplifier also comprises at least one second normally off MOS transistor. In addition, the traveling wave amplifier further comprises a normally off bias MOS transistor. The normally off bias MOS transistor forms a current mirror with at least one of the second normally off MOS transistors. An output signal of the traveling wave amplifier is tapped off on the drain line.

    Abstract: Programmable difference amplifier (1) has first load (7), first transistor (8) with a first controllable extent and a first gate connection (9) and a first adjustable current source (10). The first load, the first controllable extent and the first adjustable current source are connected in series between first and second supply voltage connections (VDD,VSS), with a second load (11), a second transistor (12), which has a second controllable extent and a second gate connection (13), and a second adjustable current source (14). The second load, the second controllable extent and the second controllable current source are connected in series between the first and second supply voltage connections. At the gate connections (9,13) a differential input signal (IN,INX) is applied. At a first conduit node (16) between the first load and the first controllable extent and at a second conduit node (15) between the second load and the second controllable extent an amplified differential output signal (OUT,OUTX) is applicable. A counter coupling device (17) for the adjustment of the amplification of the differential amplifier has a programmable resistance value and is connected between third and fourth conduit nodes (18,19). The third conduit node is between the first controllable extent of the first transistor and the first adjustable current source. The fourth conduit node is between the controllable extent of the second transistor and the second adjustable current source. To the counter coupling device the programming signal (CTRL) is applied.

    Abstract: A phase-modulated signal ( 1 ) is divided into an in-phase component and a quadrature-phase component. The in-phase component is supplied to a first one-bit analogue/digital converter ( 25 ) and the quadrature-phase component is supplied to a second one-bit analogue/digital converter ( 26 ), output signals ( 8; 9 ) of the one-bit analogue/digital converters ( 26; 27 ) being evaluated for determining data modulated onto the phase-modulated signal ( 1 ). The one-bit analogue/digital converters may be constructed as simple comparators ( 26; 27 ).
