An integrated switched-capacitor signal processing design system

Optimization in switched circuits design using constraint programming

“…Furthermore, considered the characteristics of the constraint programming modeling, the recent developments are to design the SC filters [10][11][12][13][14]. All of the above experiment results have shown an impressive impact on improving the efficiency of analog circuits.…”

“…In order to more efficiently minimize the capacitor area and capacitance spread, new approaches for the design of IIR SC circuits are presented [11][12][13][14][15]. We can just define them as pure nonlinear objectives and solve a set of nonlinear constraints, but it will always suffer from no consistent solution or no solution because the objectives and the corresponding the nonlinear constraints have too complicate models.…”

“…In the literature, a variety of analog circuit design examples using constraint programming have been presented [3][4][5][6][7][8][9][10][11][12][13][14], from Operational Amplifier (OAs) to capacitance assignment. They are partly summarized as the following:…”

“…Consequently, it may yield grossly inaccurate performance predictions, which have usually failed to make the transition from research to practice, due to primarily to the prohibitive effort required to derive the complex equations [5][6]. Based on this reason, nowadays there have been increased interests in analog circuit design using constraint programming modeling, which allow for more flexibility than standard equationbased algorithms [3][4][5][6][7][8][9][10][11][12][13][14].…”
