A mixed-signal integrated circuit that includes: a global reference signal source; a first summation node and a second summation node; a plurality of distinct pairs of current generating circuits arranged along the first summation node and the second summation node; a first current generating circuit of each of the plurality of distinct pairs that is arranged on the first summation node and a second current generating circuit of each of the plurality of distinct pairs is arranged on the second summation node; a common-mode current circuit that is arranged in electrical communication with each of the first and second summation nodes; where a local DAC adjusts a differential current between the first second summation nodes based on reference signals from the global reference source; and a comparator or a finite state machine that generates a binary output value current values obtained from the first and second summation nodes.

An integrated circuit and method are provided for performing weighted sum computations. The circuit includes: a plurality of current generators interconnected and arranged into pairs, a positive summation node, a negative summation node, and an input generation circuit. For each pair of current generators, the control terminal of each element is electrically connected to an input node. One of the current generators has its drain connected to the positive summation node while the other current generation element has its drain connected to the negative summation node. The remaining terminals on both current generators are connected to a reference, which may be shared. Each pair of current generator source predetermined amounts of current onto the two summation nodes when the following conditions occur: the input node is at an activation voltage, and the two summation nodes are at a predetermined target voltage.
