Free electronic circuit design and schematic diagram
Generally, specifically combined ICs perform a control task. We can carry out simple controls using analog ICs, such as operational amplifier circuitry. The basic component of “Control Electronics” is an integrated circuit (IC). IC is a small electronic device made out of a semiconductor material. According to equation 1, this analog circuit calculates PID control response. Sensor signal VIN is […]

The purpose of developing this circuit is to allow watch crystals to be used in an existing CMOS oscillator circuit that was to run from a 12 V supply. But there is a problem, these crystal only work uo to a supply voltage of about 6V. If the supply voltage is more than 6 V then the crystal will be […]

The strength of a radiated signal from a transmitter is measured by this circuit. It is commonly used by model airplane builders to check whether their transmitter are really transmitting the radio signal. One can quickly determine whether the problem lies on the transmitter or the receiver module using this FS meter. The only active element in this circuit is […]

If you are traveling, you might need this device to charge your gadget along the way, since it is much cheaper to buy some standard AA batteries for backup than buying several rechargeable batteries of your gadget type. Below is a charger that more efficient than linear regulator like the “7805” while you are on the go. The most important […]

A dual benefit for battery-powered portable devices is provided by Class D audio amplifier. The produce much less power dissipation than do their linear cousins and they enhance battery life. Those features make this device an ideal candidate for controlling speed and direction in small electric motors. The standard application circuit for a class D audio amplifier is shown on […]

The circuit diagram below shows us about a form of PID controller. The input signal is buffered and amplified by a non-inverting amplifier and the gain of this stage defines the proportional gain P of the controller.The amplified error signal passes in parallel through an integrator (top) a unity-gain amplifier (middle) and a differentiator (bottom) all of which have inverting […]

Based on the squaring property of two back-to-back diodes connected across output and inverting input of the op-amp, IC1B forms a rather straightforward fuzz circuit. The squared output signal coming from IC1B is converted into a triangle-shaped waveform by IC1C and related components. IC1D is wired as a virtual-earth mixer, summing the linear, squared and triangle-shaped signals coming from IC1A, […]
