The circuit is an inverter set up as a linear amplifier. Adding the· crystal and capacitors to the feedback path, we turn the amplifier into an oscillator and force it to oscillate at, or least very near, the crystal"s resonant frequency. Trimmer capacitor.... -
The JFET Pierce oscillator is stable and simple. It can be the clock of a microprocessor, a digital timepiece or a calculator. With a probe at the output, it can be used as a precise injection oscillator for troubleshooting. .. -
The crystal used in the topology of Figure 1 can be either a fundamental AT-CUT or BT-CUT. A BT-CUT crystal has poor frequency stability over temperature compared to an AT-CUT. This topology uses a parallel crystal and not a series crystal... -
An economical and commercially available quartz temperature sensor, Y1 and IC1, an LTC-485 RS485 transceiver in transmitter mode, form a Pierce crystal oscillator. The sensor, an Epson HTS-206, presents a nominal frequency of 40 kHz at 25°C and a temperature.... -
The Pierce-gate oscillator of Figure 1 is well recognized by most designers, but few understand how to specify the crystal correctly. The crystal used in the topology of Figure 1 can be either a fundamental AT-CUT or BT-CUT. A BT-CUT crystal has poor.... -
This circuit is conventional Pierce type oscillator that uses a JFET. The circuit uses fundamental mode crystals. It has decent performance and reliability if... -
a Pierce "aperiodic" oscillator driving a non-neutralized power amplifier for a multiband Morse code transmitter that requires just one coil and minimum adjustment. And then one day you happen to unplug the oscillator tube only to find that it still works!.... -
The Pierce oscillator is a very simple circuit and as with the ring oscillator also uses inverters (actually just one inverter will do). The principle of operation, however, is very different. While the ring oscillator exploits the incremental propagation.... -
This circuit is conventional Pierce type oscillator that uses a JFET. The circuit uses fundamental mode crystals. It has decent performance and reliability if we use a low noise JFET. This is the figure of the circuit. The feedback is controlled by the C1.... -

A Pierce Oscillator is a type of oscillator that uses a crystal instead of a parallel-resonant circuit [LC circuit]. A pierce oscillator also uses the voltage developed from a tap between two capacitors in the tank circuit, as shown to the right. range. Both.... -
Simple network design is a key feature of the Pierce circuit, as these 1-MHz oscillators illustrate.Operating the crystal slightly above resonance (Fig.21-5a) requires only one high-gain transistor stage.Operating it exactly at series resonance (Fig. 21-5b).... -
The oscillator uses a fundamental quartz crystal, and the oscillation frequency can be up to 10MHz. Oscillator circuit is tuned to the resonant frequency. Capacitor C requires below 4.7pF, and it is connected to a follower to isolate the quartz crystal.... -
The JFET Pierce oscillator is stable and simple. It can be the clock of a microprocessor, a digital timepiece or a calculator. With a probe at the output, it can be used as a precise injection oscillator for troubleshooting. Attach a small length of wire at.... -
This is a simple JFET pierce crystal oscillator. We can use a wide frequency range of crystal using this circuit without circuit modification. Here is the....

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.....
