Two different low-dropout (LDO) voltage regulators are optimized by applying the Non-Dominated Sorting Genetic Algorithm II (NSGA-II). First, from a sensitivity analysis a set of design variables are selected to establish a reduced chromosome for performing multi-objective optimization by NSGA-II. The computed sensitivities are used to reduce the search spaces for the design variables included into...
A low-dropout (LDO) voltage regulator is optimized by evolutionary algorithms. Basically, tolerance analysis is performed alike a worst-case analysis within SPICE to rank the circuit elements presenting higher sensitivities, and according to the target specifications associated to two objectives, namely: Power Supply Rejection (PSR) and output capacitor value. The results from the tolerance analysis...
