In Seemingly Simple Circuits: Transresistance Amplifier, Part 1– Approximating Op-Amps, the op-amp was approximated from a single-pole, finite gain amplifier to an infinite-gain, single-pole op-amp, ...

This cable tv amplifier circuit is a rf amplifier designed to be quickly installed between two coaxial cables. Both input and output impedances are compatible with 75 Ω cables. The main amplifier si ...

Logic Noise is an exploration of building raw synthesizers with CMOS logic chips. This session, we continue to abuse the 4069UB as an amplifier. We’ll turn the simple unity-gain buffer of last session ...

Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...

In a signal-conditioning op-amp application there are a number of different approaches to take, what noise and SFDR advantages might one offer over another. Download this Basics of Design article.
