RIPPLE MONITORING
First Claim
1. A ripple monitoring circuit for generating information indicative of a failing component in a power supply, the ripple monitoring circuit comprising:
- at least one input that receives a ripple signal from the power supply that has a ripple component;
a quantization circuit that repeatedly quantizes the amplitude of the ripple component; and
a ripple amplitude statistics counter bank that counts and stores the number of times that different quantized amplitudes or different ranges of quantized amplitudes of the ripple component occurred.

Abstract
A ripple monitoring circuit may generate information indicative of a failing component in a power supply. At least one input may receive a ripple signal from the power supply that has a ripple component. A quantization circuit may repeatedly quantize the amplitude of the ripple component. A ripple amplitude statistics counter bank may count and store the number of times that different quantized amplitudes or different ranges of quantized amplitudes of the ripple component occurred.
A ripple monitoring circuit may generate information about a power supply. At least one input may receive a ripple signal from the power supply that has a ripple component. A ripple measurement circuit may measure a characteristic of the ripple component. A storage circuit may store information about the measurement. A comparison circuit may compare information stored in the storage circuit with a threshold value and indicate when the stored information meets or exceeds this threshold value.
