Nonlinear multiport resistors are the main ingredients in the synthesis of nonlinear circuits. Recently, a particular PWL representation has been proposed as a generic design platform [1]. In this paper, we present a mixed-signal circuit architecture, based on standard modules, that allows the electronic integration of nonlinear multiport resistors using the mentioned PWL structure. The proposed architecture is fully programmable so that the unit can implement any user-defined nonlinearity. Moreover, it is modular: an increment in the number of input variables can be accommodated through the addition of an equal number of input modules.
