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, …
