Kami mencadangkan di sini algoritma reka bentuk berorientasikan Spice sepenuhnya bagi op-amp untuk mencapai keuntungan maksimum di bawah penggunaan kuasa yang rendah dan kadar slew yang ditetapkan. Algoritma pengoptimuman kami adalah berdasarkan kaedah turunan paling curam yang terkenal digabungkan dengan pengaturcaraan tak linear. Algoritma ini direalisasikan oleh litar RC setara dengan ABM (model tingkah laku analog) Spice. Arah kecerunan ditentukan oleh analisis litar sensitiviti. Parameter optimum boleh didapati pada titik keseimbangan dalam tindak balas sementara litar RC. Walaupun masa pengoptimuman adalah lebih cepat daripada alat reka bentuk lain, hasilnya mungkin kasar kerana model transistor yang mudah. Jika nilai parameter yang jauh lebih baik diperlukan, ia boleh dipertingkatkan dengan simulator Spice dan/atau alatan lain.

Abstract: We propose here a fully Spice-oriented design algorithm of op-amps for attaining the maximum gains under low power consumptions and assigned slew-rates. Our optimization algorithm is based on a well-known steepest descent method combining with nonlinear programming. The algorithm is realized by equivalent RC circuits with ABMs (analog behavior models) of Spice. The gradient direction is decided by the analysis of sensitivity circuits. The optimum parameters can be found at the equilibrium point in the transient response of the RC circuit. Although the optimization time is much faster than the other design tools, the results might be rough because of the simple transistor models. If much better parameter values are required, they can be improved with Spice simulator and/or other tools.

AB - We propose here a fully Spice-oriented design algorithm of op-amps for attaining the maximum gains under low power consumptions and assigned slew-rates. Our optimization algorithm is based on a well-known steepest descent method combining with nonlinear programming. The algorithm is realized by equivalent RC circuits with ABMs (analog behavior models) of Spice. The gradient direction is decided by the analysis of sensitivity circuits. The optimum parameters can be found at the equilibrium point in the transient response of the RC circuit. Although the optimization time is much faster than the other design tools, the results might be rough because of the simple transistor models. If much better parameter values are required, they can be improved with Spice simulator and/or other tools.
