Find Resonator/Oscillator Capacitance/Inductance at 1 MHz

  • Thread starter AskTheGenius
  • Start date
In summary, the conversation is about determining the capacitance and inductance required for a 1 MHz resonator/oscillator. The options for solving this include starting with an assumption and solving for the others, using a program to determine suitable values, and finding suitable inductors. The ferrite rod antenna in transistor radios is mentioned as an example of a resonator at 1 MHz.

http://en.wikipedia.org/wiki/RLC_circuit" It's under resonance frequency.

You'll have to start with an assumption. Assume one of the following three, and you can solve for the others:

C
L
X of C and L

At resonance, Xc = XL = 2*pi*f*L = 1/2*pi*f*C

You could try these:

16 uH... 1592 pF

24 uH ... 1061 pF

32 uH ... 796 pF

Try to download the following program:

I set the reactance to about 200 ohms and let the program work out suitable L and C values.
Watch the units.

Then the hard part is finding suitable inductors. The ferrite rod antenna in transistor radios resonates at 1 MHz with about 200 pF.

Welcome to the PF, Ask. What'cha making?
 

FAQ: Find Resonator/Oscillator Capacitance/Inductance at 1 MHz

How do I calculate the required capacitance or inductance for a resonator/oscillator at 1 MHz?

To calculate the required capacitance or inductance for a resonator/oscillator at 1 MHz, you can use the formula: C = 1/(4π²f²L) for capacitors and L = 1/(4π²f²C) for inductors. Simply plug in the frequency (1 MHz) and solve for the unknown variable.

How do I find the resonant frequency of a circuit using capacitance or inductance at 1 MHz?

To find the resonant frequency of a circuit using capacitance or inductance at 1 MHz, you can use the formula: f = 1/(2π√LC). Plug in the capacitance and inductance values and solve for frequency. This will give you the resonant frequency of the circuit.

Can I use any type of capacitor or inductor for a resonator/oscillator at 1 MHz?

No, not all capacitors and inductors are suitable for resonator/oscillator circuits at 1 MHz. It is important to choose components with the correct capacitance or inductance values and also make sure they can handle the frequency and power requirements of the circuit.

What is the importance of choosing the right capacitance/inductance for a resonator/oscillator at 1 MHz?

The capacitance and inductance values are crucial for the proper functioning of a resonator/oscillator at 1 MHz. Choosing the wrong values can result in a circuit that does not resonate at the desired frequency, causing it to malfunction or not work at all.

How do I ensure the accuracy of my calculated capacitance or inductance for a resonator/oscillator at 1 MHz?

To ensure the accuracy of your calculated capacitance or inductance for a resonator/oscillator at 1 MHz, it is important to use precise measurement tools and follow the appropriate formulas. Additionally, double-checking your calculations and consulting with other experts in the field can also help verify the accuracy of your results.
