Abstract
It is described a mathematical solving circuit (100) comprising: a crosspoint matrix (MG) including a plurality of row conductors (Li), a plurality of column conductors (Cj) and a plurality of analog resistive memories (Gij), each connected between a row conductor and a column conductor; a plurality of operational amplifiers (OAi) each having: a first input terminal (IN1i) connected to a respective row conductor (Li), a second input terminal (IN2i) connected to a ground terminal (GR) at least one operational amplifier (OAi) of the plurality being such to take the respective first input terminal (IN1i) to a virtual ground.
