I have personally used the Twin-T RC oscillators a lot and I find it very interesting, mainly because it is designed to generate a sinewave output. It is ideal for fixed-frequency applications much like the Wien-bridge oscillator. The name “Twin-T” oscillator comes from the fact that it employs two “Tee”-shaped RC networks in the feedback […]

Decibel Calculations: From Basics to Advanced Applications
We usually think of decibels as being used to measure loudness. But when designing amplifier and filter circuit layouts, we typically come across numerical values that have extremely wide ranges. For example, a total gain of 665 (19 multiplied by 35) is obtained through cascading two amplifier stages with power gains of 19 and 35 […]
