Patent ID: 6995608

Claim:
A reconfigurable analog cell (RAC) ( 100 ) comprising an input (In), an output (Out) and a first control input (Control — In) for generating at the output a vector of at least one signal which is the result of at least one of a plurality of transfer functions (Out — V), having a set of poles, from an input signal (In — S) applied to the input, the reconfigurable cell ( 100 ) further comprising a plurality of admittances y ab each of them having a first terminal (a) and a second terminal (b), a plurality of switches (SW), each of them having a first switch terminal (SW 1 ), a second switch terminal (SW 2 ) each switch having an ON state, in which the first and the second switch terminals are connected together, and an OFF state in which the switch terminals are not connected to each other, each switch further having a control terminal (CS — RAC) for controlling the state of any switch SW by a binary signal received through the Control — In, the plurality of switches SW comprising a first plurality of switches and a second plurality of switches, a plurality of internal nodes ( 1 , 2 , 3 , 4 , 5 , 6 , 7 ), one of the nodes being designated as the reference node, characterized in that each of the first terminals (a) of the admittances y ab is coupled to the first terminals SW 1 of the first plurality of switches, each of the second terminals (b) of the admittances y ab is coupled to the first terminals SW 1 of the second plurality of switches, each one of the second switch terminal SW 2 of the first plurality of switches and of the second plurality of switches is coupled to at least one node of the plurality of nodes, the arrangement being such that when a control vector V — In is applied through the Control — In only one of the switches from any plurality is ON, realizing a particular state of a plurality of possible states (PSPPS) of the RAC ( 100 ), each of the states defining a transfer function having the said set of poles.
