555 Timer as Astable Multivibrator (Oscillator)

555 Timer as Astable Multivibrator (Oscillator) PUBLIC

A 555 timer can be used with a few resistors and a capacitor to make an oscillator, switching states as the capacitor charges and discharges.

Capacitively Loaded Emitter Follower

Capacitively Loaded Emitter Follower PUBLIC

An emitter follower is supposed to have its output voltage follow changes in its input approximately 1 to 1, but fast input edges and a capacitively loaded output lead to undesired and asymmetric...
