Realization of couplings in a polynomial type mixed-mode CNN

In this paper realization of couplings between cells in a polynomial type mixed-mode cellular neural network (CNN) is analyzed. One quadrant operation is required from the analog multipliers and polynomial circuits because in a mixed-mode CNN extension to four quadrant operation can be done digitally. A one quadrant multiplier is analyzed and simulated with HSPICE. Furthermore, circuits for generating second and third order polynomial terms of cell output are analyzed and HSPICE simulations are shown.
