This paper presents an application of the Interior-Point method of optimization to the design of a CMOS analog integrated circuit. We have chosen the minimum voltage log-domain Seevinck's integrator, where devices operate in weak inversion, so that model equations, required bias conditions and circuit architecture lead to nonposynomial general equations and restrictions that are represented by nonconvex functions. The optimization problem is formulated and the MATLAB optimization toolbox is used to find transistor dimensions and biasing currents. Circuit simulation is performed with these results.
