Testing PSRR with High-Frequency Ripple
ثبت نشده
چکیده
This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many electronic systems such as RF and wireless systems, power management systems, data converters, clocking systems, and high-speed serial interface systems. PSRR measures how well a circuit rejects ripple coming from input power supply at various frequencies, measuring system performance with a ripple (e.g., sinusoidal ripple) of specific amplitude and frequency added to the power supply, and verifying that it meets the required performance specifications.

Improving Linear Regulator Power Supply Ripple Rejection (PSRR) and Output Noise
The PSRR of a linear regulator is determined by three factors: 1. The PSRR of the bandgap voltage reference, whose output ripple affects the output ripple of the linear regulator up to the roll-off frequency of the bandgap. 2. The open-loop gain of the feedback loop (AV), which is roughly equal to the open-loop gain of the error amplifier, up to the 0dB (unity gain) crossover frequency of the l...
