Free-running-multivibrator


Posted on Jan 9, 2013

This is the simplest of any programmable oscil lator circuit, since only one stable timing capacitor is required. The output square wave is about 25 V pk-pk, and bas rise and fall times of about 0.5 p,s.

If a programmable attenuator circuit is placed between the output and the divider network, 16 frequencies can be produced with two HA-200 "s and still only one timing capacitor.
