High psrr bandgap
WebOct 1, 2024 · The bandgap reference (BGR) is one of the most popular reference voltage generators that successfully achieve the requirements [1]. In order to generate a stable reference voltage for high precision applications, it is necessary that the reference circuit should have high power supply rejection ratio (PSRR) [2], [3]. WebMar 29, 2006 · PSRR. PSRR is defined as the linear regulator’s ability to eliminate output ripple caused by input variations. High PSRR values are desirable over the frequency range that is critical to the linear regulator, typically 10 Hz to 10 MHz. Mathematically, PSRR is the reverse gain of the output ripple over the input ripple at a particular frequency.
