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.

op-amp   oscillator   rc   time-constant  



Switch SW1 closes at t=0. Circuit is in equilibrium just before t=0. Opamp OA1 is ideal. I'm have trouble calculating the time constant for the capacitor's waveform. Can anyone help? VM1 = (-Rf/Ri) x...

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...
