Completed test1 -Investigation of power supply effect on high resolution ADC.

#1 Proposal
Nowadays SMPS (switching mode power supplies) are used intensively. They have many advantages over linear regulators, but they are inducing switching noise to the power supply lines. For electronic systems, power supply lines are considered as an input signals that will be transferred to the output. Digital systems are usually not sensitive to this noise. But analog systems suffer a lot from this property and many times SMPS makes analog systems useless. In order to overcome this effect engineers have to filter analog supplies from any switching noises.

This project will study the effects of switching noise that comes from switching mode power supplies on a high resolution ADCs (above 20bit). Students will build a PCB board with 24bit ADC on it. Students will build several options of SMPS on the board and study effects of each configuration on the ADC output (both time and frequency domain).

Students will write a brief summary of their study and file this summary to EDA for publishing.
