EEVBlog #1116 – The Capacitance Multiplier

Circuit building block time. The capacitance multiplier and how it gives almost negligible power supply ripple compared to a voltage regulator. Whiteboard theory and then some bench demonstrations and experiments. Plus a twist at the end that proves that the “Capacitance multiplier” is perhaps one of the most mis-named circuits ...

EEVblog #1046 – Mysterious Digital Voltage Doubling

Dave explains and demonstrates how out of phase digital signals can effectively double your voltage. The magic of moving your reference point. And how you can verify this with a differential probe. A question bought up in the comments of the previous LCD driving video. The HVP70 High Voltage Differential ...
