Audiophiles spend a lot of time and effort worrying about audio specs like Total Harmonic Distortion (THD). Makes sense, because THD affects the quality of audio reproduction. However, THD can also ...

What is a transfer function? How to implement a Laplace transform in LTspice. Analyzing transfer functions in the frequency and time domains. Looking at compensator design in LTspice. Transfer ...

The essentials of current-mode-control modeling. What are modified average models? Verifying new LTspice models for different, previously unsupported power-supply topologies. When a power-supply ...

LTspice has a way to model electromechanical switches, which I have occasionally tried to use to simulate dc-dc converters without all the hassle of setting up mosfets and appropriate driver circuits.

I was concocting a rather silly low-pass filter design, when I remembered that Messrs Sallen and Key did it better in the 1950s, and decided to use their two-pole design to implement a Butterworth ...

Design and implement a minimalist but practically usable regenerative receiver capable of HF reception from 3-30 MHz. Analyze the key aspects of the receiver’s operation (e.g. behavior of the ...
