Analog meter normally doesn’t have high impedance since they don’t have buffer circuit inside. With active buffering, the input impedance of this circuit depends on the impedance of the op-amp. You can use other op-amp for higher impedance, but a low-cost 741 is enough for may application. The rectification inside the feedback loop path remove the effect of diode’s voltage […]

Usually, LED is powered by DC supply, but this circuit can make the LED can be powered by AC supply. This circuit can be used as power indicator for Water pump. There are two circuit versions of AC-powered LED presented here. First is circuit for US or Canadian 110-120V 60Hz AC lines and European or Australian 220-230V 50Hz AC lines. […]

Current mode amplifier has the benefit of higher frequency operation, and LM359 comes as operational amplifier with this type op amplifier. Current mode (Norton) amplifier can be used in video, RF, of high speed communication design. You can apply this current mode noninverting amplifier in wide variety of applications, make sure this circuit performance (shown as the frequency response curve) […]

Every electronic device that boost electrical signal can be called an amplifier. The various amplifier types only differ in some specific features such as: bandwidth, input range, input-output impedance, or gain. Video amplifier is used to amplify the intensity information of a video signal, a signal that is used to control the grid of a CRT (Cathode Ray Tube) to […]
