Many people who get analog electronics still struggle a bit to design oscillators. Even common simulators often need a trick to simulate some oscillating circuits. The Barkhausen criteria state that ...

In electronics, negative resistance is an oddball property which occurs in a few nonlinear components. Just think that an increase in voltage across a device’s terminals results in a decrease in ...

The LTC6902 from Linear Technology is a precision, easy-to-use, resistor programmable oscillator that provides up to four output phases. Its frequency can be varied from 5 kHz to 20 MHz, with 1.5% ...

Of all the low-frequency oscillator configurations, the Wien Bridge has to be the friendliest and easiest to get along with. Like a faithful dog, it behaves itself regardless of the weather, is not ...

More than a half-century old, the ubiquitous and mind-bogglingly useful 555 analog timer has become a perennial object for both kudus and criticism. Most of the former and some of the latter is ...
