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 #1085 – Bypass Capacitors Visualised!

An in-depth practical visualisation of how bypass capacitors work at both high and low frequencies. Bulk decoupling capacitors vs bypass capacitors. Capacitor placement and types are tested and the results examined. How package inductance can have a large effect. Loop area and what is means, it’s impact on EMC emissions, ...

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 ...

EEVblog #1044 – LCD Technology Tutorial

Part 1 in a series of videos on designing a custom LCD display. This tutorial covers how LCD displays work, the 3 different types of interface (DIP, Elastomeric, Flex), the three different optical types (Reflective, Transflective, and Transmissive), and the two different types of drive (Static vs Dynamic) Microchip AN658 ...
