Voltage Reference circuit
Adjustable Current Source circuit
Voltage reference ic

Micropower Voltage Reference with LM4250A low-drift voltage reference can be easily made by converting a zero temperature coefficient current to a voltage. JFETs biased slightly below pinch-off exhibit a zero temperature coefficient drain current (ID) …
Voltage Reference using LM334 This Voltage Reference Circuit. It used LM334 (ADJUSTABLE CURRENT SOURCES IC)
By fix the trend is stable. It make the pressure that pay to come out have tall stability. By can fine decorate VR1 10K Adjust Voltage Output. And You can use Voltage Input power supply at +2.5V to +20V. …..
Stable Zener Reference Nowadays some first-rate voltage references are available. Take the LM385 for example: this is available for different voltages and even comes in an adjustable version. What is more, the current consumption may be kept very small (10 µA). But as often happens, you may not have one to hand when you need one for an experimental circuit….

  • How to make simple electronic buzzer April 21, 2014
    A electronic buzzer is simple. But useful well worth and the price is lower than 1$. By use just a 9-volts battery only. So without worrying about electrical leakage or electric shock from 220V to buzzer. Unless also has LED will glow. Show that the circuit the normal operation as well. The working of circuit. […] […]

  • Automatic night light switch using 741 op-amp. April 21, 2014
    We’ve watched a lot of Automatic night light switch circuits. Which I like to use a transistor as base. But now we lets to see IC-op-amp. It is also very simple. As my feelings It has high sensitivity more than one, and with great high accuracy. How does it works. A light detector component, we […] […]

  • Simple Two digits counter using CD4026 April 19, 2014
    This is a simple two digit counter using CD4026 as main parts can display with LED 7 segment 0-99 number There is a reset button to restart. It can be applied to, for example, counting products, counting people into the library, and more. The working principle As circuit in Figure 1. The IC1, IC2-CD4026 4026 […] […]

  • Morning alarm with sunlight using IC-4011 April 17, 2014
    This is simple circuit that we makes in hobby time or toys for my son but really uses. It will have sound alarm when morning like a normal clock alarm with lighting sensor same clock. We use a IC-4011 CMOS only one and a few components also can generate pulsating tone like a general clock. […] […]

  • Simple Electronic clock sound using IC4011 April 17, 2014
    The sound of insects such as crickets, cicadas, resulting from flutter briefly. We can use a multivibrator to connects as sound generator circuit to imitate these insects sound. Some electronic clock alarm tone also sounds similar to these insects. As Figure 1 is simple clock alarm sound generator that can assemble on a breadboard right […] […]
