Low power consumption monostable circuit diagram

Published:2011/3/30 21:40:00 Author:Ecco | Keyword: Low power consumption, monostable

The circuitry shown as below, it includes a four 2 input port and NOT-gate CD4011 and a CMOS type 555, as a result whether it is inthe timing period of quiescent or high output level, it consumes very low. The portal 3 of CD4011, portal 4 constitute RS trigger. Because the whole circuitry presents in closed cycle, the pulse width is decided by the RC time constant, namely td=the 1.1 R1 C1.   (View)

The circuit diagram of TTL level displayed by LED

Published:2011/3/30 21:19:00 Author:Ecco | Keyword: TTL level, LED

This circuitry could be used to observe the TTL electrical level when there's no cathode-ray oscillograph . 74123 integrated circuit contains two trigger type of monostable harmonic oscillators with input of zero clearing, and they are marked as A1 andA2 in this circuit respectively. When the input level changes, the tmonostable harmonic oscillator will light more light emitting diode. Because single firm extended the pulse width, even if the input brain is very narrow, naked eye can still arguing the brightness of diode. The exhibit explains three light-emitting diodes mean of different states.   (View)

Ratio of the unknowns circuit diagram

Published:2011/3/29 20:11:00 Author:Ecco | Keyword: Ratio of the unknowns

This circuit is used as the situation of two signals share the same input line, for example, two leds irradiate a single photocell alternately. To measure the ratio of two unknowns, the precision better than 1%. During the period of T1, the input signal is sampled by S2, and storaged in C2, so that to make a comparison with reference voltage, the result of which can be obtained by the amplifier network AFE, added to gain control elements CLM6000. The adjusting signal gain of closed loop is increased, and the denominator of ratio is equal to reference voltage. And the molecular corresponding to T2 multiplied by the same gain, so the output of molecular direct ratio to the needed unknow value B/A .   (View)
