Noise injection for power noise susceptibility test for memory systems

A noise injection system comprising:

• a power selector configured to deliver a voltage at a first level or a voltage at a second level according to a frequency level indicated by a frequency select signal;
• a noise signal relay configured to receive a frequency noise signal and to deliver according to the frequency level indicated by the frequency select signal a low frequency noise component when the frequency select signal indicates a low frequency level of the frequency noise signal and a high frequency noise component when the frequency select signal indicates a high frequency level of the frequency noise signal;
• and
• an amplification assembly, responsive to the frequency select signal and configured to
• receive the first level voltage or the second level voltage based on the frequency level of the frequency select signal,
• receive and amplify the high frequency noise component when the frequency select signal indicates a high frequency level, and
• receive and amplify the low frequency noise component when the frequency select signal indicates a low frequency level.

A method for injecting noise into a device under test (DUT), the method comprising:

• selecting a first voltage level or a second voltage level according to a frequency level indicated by a frequency select signal;
• transmitting power at the first voltage level to an amplification assembly when the frequency select signal indicates a low frequency level, and transmitting power at the second voltage level to the amplification assembly when the frequency select signal indicates a high frequency level;
• delivering a low frequency noise component of inputted frequency noise to a power amplifier of the amplification assembly for amplification when the frequency select signal indicates the low frequency level, and delivering a high frequency noise component of the inputted frequency noise to an operational amplifier of the amplification assembly for amplification when the frequency select signal indicates the high frequency level;
• and
• outputting power at the first voltage level and the amplified low frequency noise component when the frequency select signal indicates the low frequency level, and outputting power at the second voltage level and the amplified high frequency noise component when the frequency select signal indicates the high frequency level.
