ely. FET amplifier transistor amplifiers to be like that, configured as a common source (equivalent to a total emission) amplifier, a common-gate (equivalent common base) amplifier and a common drain (equivalent to common collector) amplifier. And it can also form a common source common source amplifier, total gate amplifier common source and common drain amplifier source altogether complex circuit form, as 8-50 and crystal corresponding transistor amplifier FET amplifier also has the characteristics of the corresponding 6 is similar to the transistor circuit to be noted that in FET amplifier, since the high input resistance of FET gate, the front and rear stage circuit when the cascade circuit, basically without considering the impact on the post-stage circuit of the preceding stage, thereby simplifying the design and debugging. However, because of its high input impedance A, distributed capacitance, inter-electrode capacitance and the Miller effect capacitance affect more than the transistor circuits are critical, therefore, still in use in high-frequency circuits and gate circuits and total common source circuit, a total common source-drain circuit peers formula to improve the stability and frequency characteristics of the amplifier. In the low-frequency amplifier circuit, due to the high input impedance FET, easily induced hum and other noise signal, because this process should pay more attention to shielding and other issues.
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.....
