Voltage Gain of Hartley Oscillator Formula:
| From: | To: |
The Voltage Gain of Op-Amp in Hartley Oscillator quantifies the increase in voltage amplitude between the input and output of the circuit. It is a crucial parameter in determining the oscillation condition and stability of the Hartley oscillator circuit.
The calculator uses the Hartley Oscillator formula:
Where:
Explanation: The voltage gain is determined by the ratio of the two inductances in the tuned LC tank circuit of the Hartley oscillator.
Details: Accurate voltage gain calculation is essential for designing stable oscillator circuits, ensuring proper oscillation conditions, and maintaining desired output amplitude in Hartley oscillator applications.
Tips: Enter both inductance values in Henry. All values must be valid positive numbers greater than zero for accurate calculation.
Q1: What is the typical range of voltage gain in Hartley oscillators?
A: The voltage gain typically ranges from fractions to multiples, depending on the inductance ratio, but must meet the Barkhausen criterion for sustained oscillations.
Q2: How does inductance ratio affect oscillator performance?
A: The inductance ratio directly determines the voltage gain, which affects the oscillation amplitude, stability, and startup conditions of the oscillator.
Q3: Can this formula be used for all Hartley oscillator configurations?
A: This formula applies specifically to the basic Hartley oscillator configuration with two series-connected inductors forming the tank circuit.
Q4: What are the practical considerations when selecting inductances?
A: Consider quality factor (Q), mutual coupling between inductors, frequency requirements, and physical size constraints when selecting inductance values.
Q5: How does temperature affect the voltage gain calculation?
A: Temperature variations can affect inductor values due to thermal expansion and changes in core properties, which may require compensation in precision applications.
