Crystal Oscillator II
The world is full of xtal oscillators twiddled by digital designers lacking in the analog design knowledge necessary. Just look at all the PC real time clocks that lags or leads by several minutes per day. And they eat backup...
DIY Crystal Oscillator Circuit
A very simple DIY crystal oscillator circuit that uses a quartz crystal for frequency stability and a suitable RF transistor. It employs a second or third harmonic crystal for operation.
This DIY crystal oscillator circuit is designed to generate stable oscillations...
Micro Power AM Broadcast Transmitter
This circuit utilizes a 74HC14 hex Schmitt trigger inverter as a square wave oscillator to drive a small signal transistor configured in a class C amplifier setup. The frequency of the oscillator can be either fixed using a crystal or...
oscillation Oscillator circuit
The first thing to understand is how capacitor C1 is related to the resonance frequency f of the circuit. It appears that selecting a frequency allows for the automatic determination of the necessary value for C1. There are uncertainties regarding...
Colpitts oscillator FM transmitter
Its frequency depends on the capacitance of the vary cap diode. The center frequency is changed by varying the biasing voltage of the vary cap through the 47K pot. You can use a 75cm telescopic antenna or simply a length...
Timing-threshold-and-load-driver
Power is applied to the circuit with the initiate switch open. The 25 µF capacitor charges through the A14 diode, or an equivalent, and a 2.2 kΩ resistor to the full supply voltage. When the initiate switch is closed, the...
Quartz crystal sine wave oscillator circuit
The image depicts a sine wave oscillator that consists of a quartz crystal (SJT) and gate A of the hex inverter IC CD4069. Compared to a standard RC phase-shift oscillator, the frequency stability of a crystal oscillator can achieve 10^-5...
Metallic pipe detector
This circuit employs a 15-kHz oscillator coil. When metal is removed from the energy field, the oscillator voltage is rectified and compared to a reference. A decrease in oscillator voltage activates comparator IC2, causing D4 (LED) to turn off.
L1 consists...
Switchable Output Crystal Oscillator
This oscillator circuit allows crystals to be electronically switched by logic commands. To understand the circuit, it is helpful to initially disregard all crystals and consider all diodes as shorts while their associated 1kΩ resistors are treated as open. The...
