This is a circuit of Wideband RF amplifiers. This circuit use current-feedback components like the THS3202. The THS3202 was chosen because it has fast slew rate and wide bandwidth. The amplifier voltage gain of this circuit is 20 and stage voltage gain of this circuit is 10. Here is the circuit: Compared to traditional RF circuitry, this circuit i

s simpler. This circuit just require two resistors, op amp, decoupling components and the termination. the stage gain is set by The 301-O (RF) and 16. 5-O (RG). [Source: Texas Instruments Application Note] The basis of an audio mixer is an inverting summing circuit below. For real audio mixers, a single-supply voltage is seldom used. To increase dynamic range, the designer will often push an op amp up to, and sometimes beyond it`s Continue reading †’. Not only a summing circuits, but there are also subtracting circuits. Here`s the circuit diagram: Subtracting circuit is a common application which is used to eliminate the vocal track (recorded at equal levels in both channels) from stereo recordings. R1 Continue reading †’. This is a Single Op-Amp Twin-T Band-Pass and Notch Filter circuit. This circuit uses the twin-T topology which requires one or two op amps and three resistors and three capacitors. That`s mean this topology based on a passive (RC) topology. Continue reading †’. Generation of a virtual ground is required by single-supply operation. It`s usually required at a voltage equal to Vcc/2. We can use a simple voltage divider produce Vcc/2, but it`s performance deteriorates at low frequency. The values of R1 and Continue reading †’. The figure below show an operational amplifier circuit. Closed-loop gain given by this circuit is R2/R1 when this ratio is small compared with the amplifier open-loop gain, and it`s...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
