Why 33pf capacitor is used in oscillator circuit of microcontroller?

Capacitors can be used for many purposes - for debounce of inputs, power isolation, curcuit loading. Some microcontrollers have D/A converters, oscillators, or transmitters built in and require external capacitors to operate these at specific frequencies.


What type of oscillator used in handwatches?

a crystal 32.768kHz oscillator.


Is crystal oscillator used in Varactor diode modulator?

YES


Why piezo crystal oscillator used?

Piezo-electric quartz crystals are used to define the frequency in a crystal-controlled oscillator. Quartz is a hard material that tends to oscillate mechanically at a high frequency (up to about 20 MHz) when maintained by the maintaining amplifier. The signal produced is far more stable and predictable than an L-C oscillator, especially when the crystal is placed in a dedicated oven with a controlled temperature.


Where a colpitts oscillator is used?

the Colpitts oscillator , named after the inventor of the circuit , is characterised by the use of Two Capacitors in series which are then connected in parallel across the inductor of the resonant circuit for obtaining the required frequency. The junction of the two capacitors is used for the positive feedback used for generating the oscillations. This circuit is used for High frequency oscillators , mainly due to ease of obtaining required ratio of the two capacitor values as per the circuit design. Also the two capacitors in series reduces their total equivalent value , which is not a problem as in HF circuits as the values and size is comparatively low. For information , a corresponding Low frequency circuit is called a Hartley oscillator , also named after its inventor. This uses a tapped inductor & one capacitor for the resonant circuit, since it is more easier to fabricate large value tapped inductors , than to use two bulky ( since the value of capacitors in series is reduced ) capacitors necessary for the equivalent Colpitts oscillator.

Which oscillator produces 1MHz frequency?

One type of oscillator that can produce a 1MHz frequency is a crystal oscillator. Crystal oscillators use a quartz crystal to generate stable and precise frequencies. They are commonly used in electronic devices like radios, computers, and microcontrollers to provide accurate timing signals.

YES


Differetiate between LC oscillators and crystal controlled oscillators?

LC oscillators use inductors and capacitors to generate a frequency, while crystal controlled oscillators use a quartz crystal to establish the frequency. LC oscillators can be less stable and accurate compared to crystal controlled oscillators, which offer better precision and stability. Crystal controlled oscillators are commonly used in applications where precise frequency control is essential.


Why crystal oscillator used for microcontrollers?

Oscillators are connected externally with the microcontroller to provide high frequency signal to the oscillator circuit in the microcontroller. The oscillator circuit provides the clock signal to the micro controller. Usually "PIEZO CRYSTAL OSCILLATORS" are used in micro controllers.
