We can easily use FET and Crystal to generate the frequency as Low voltage crystal oscillator Circuit, 1.5V-10V supply. It can operate at a supply voltage to 1.5 volts only and at crystal frequency 100 kHz to 10 MHz. The crystal is connected to between the drain and gate of FET-T1 BF256.
WebJan 10, 2024 · The oscillator developed around FET T1 gets its frequency solidity through a quartz crystal, X1. Here, an low-cost third-overtone series resonance crystal is employed. The oscillator is ‘forced’ to run on the third over-tone of the quartz'crystal by fine-tuning the L-C parallel tuned circuit from the drain line to 27 MHZ. WebQuart Crystal Oscillator Example No1. A quartz crystal has the following values: Rs = 6.4Ω, Cs = 0.09972pF and Ls = 2.546mH. If the capacitance across its terminal, Cp is measured at 28.68pF, Calculate the fundamental oscillating frequency of the crystal and its secondary resonance frequency.

A crystal radio receiver, also called a crystal set, is a simple radio receiver, popular in the early days of radio. It uses only the power of the received radio signal to produce sound, needing no external power. It is named for its most important component, a crystal detector, originally made from a piece of crystalline … See more Crystal radio was invented by a long, partly obscure chain of discoveries in the late 19th century that gradually evolved into more and more practical radio receivers in the early 20th century. The earliest practical … See more A crystal radio can be thought of as a radio receiver reduced to its essentials. It consists of at least these components: • See more A crystal radio tuned to a strong local transmitter can be used as a power source for a second amplified receiver of a distant station that cannot be heard without amplification.
