Due to a large number of converters in dc grids, the simulation speed using traditional electromagnetic simulation tools becomes very slow. An associated discrete circuit (ADC) switch model can improve the simulation efficiency greatly by avoiding the modification of system matrix during switching. However, existing ADC switches induce virtual power losses due to simulation errors during switching...
High-stability, high-accuracy low-dropout (LDO) voltage regulators are presented. The proposed LDOs make use of the slow-rolloff frequency compensation scheme which can enhance the stability, increase the loop gain and unit-gain frequency (UGF). This scheme is realized by introducing a dominant half-pole by virtue of three zero-pole pairs and a low-frequency pole. Post-layout simulation results show...
