Abstract (en)
[origin: EP0343719A2] A simple and space-saving circuit arrangement for forming an output signal as a linear combination of a number of input signals (S1, ..., Sn) is described. This contains only one current control element (11, ..., or 1n, respectively) for each input signal (S1, ..., or Sn respectively), particularly a transistor. The transistors are connected at one end with taps (41, ... or 4n respectively) of a chain of feedback resistors (R1, ..., Rn-1) and, at the other end, alternately to a first (31) and a second (32) output connection. The parallel connection of the feedback resistors (R1, ..., Rn-1) directly following the tap (41, ... or 4n, respectively) for the current control element (11, ..., or 1n, respectively) is dimensioned in accordance with the factor by which the input signal (S1, ..., or Sn respectively) is weighted in the linear combination. <IMAGE>
