Dual D flip-flop VCO

Published:2011/4/18 20:14:00 Author:Ecco | Keyword: Dual D, flip-flop , VCO

The chart shows the dual D flip-flop VCO. Circuit outputs a 50% duty cycle square wave signal, while the consumption of current is very low. When the input voltage is 5 ~ 12V, the output frequency ranges from 20 ~ 70kHz. First assuming the initial state of IC-A is Q = low level. At this time, VDl turns off, Vi charges to Cl through Rl. When the voltage on Cl reaches a certain voltage level, IC-A is forced to flip, its Q output is in high level, Cl discharges through VDl. At the same time, the CL input of IC-A will be transformed into low level, IC-A is forced back to Q = low level. The delay effect of R2 and C2 discharges the electricity of C1 before the IC-A returning to the state of Q = low level. The narrow pulse current of IC-A triggers IC-B, it produces a 50% duty cycle output pulse signal.   (View)

4h Timing circuit composed of 556

Published:2011/4/14 3:42:00 Author:Ecco | Keyword: 4h , Timing circuit

The figure shows 4h timing circuit which is composed of 556 dual time base circuit. To access N8281 divider network in the middle of 556 dual time base circuit, it will get a long time delay without large volume of capacitors. The first l / 2 (556) works in the way of oscillator, the period is l / f. It will produce the signal output in a N / f cycle to trigger the other half 1 / 2 (556) to add the output of oscillator to N divider network. It decides the total delay produced by the dividerto connect the divider to ⑧ pin of the second 1 / 2 (556) input terminal. Delay time is divided in 4 blocks of 30min, 1h, 2h, 4h. If connecting N8281 crossover in series additionally , the total amount of delay can be increased to days or even weeks.   (View)
