  • Analog Circuit Design
    … necessary to accomplish precise voltage regulation and avoid undesirable quantization effects, such as limit -cycle oscillations [9]. Although other modulation schemes (such as sigma -delta) can be envisaged, and other control schemes with varying switching frequency (such as sliding-mode and hysteretic control) can be used, the use of constant-frequency pulse-width modulation is widespread in switching power …
