Calculating Operating Frequency for Oscillators
BJT Phase Shift Oscillator
To calculate the operating frequency of the BJT phase shift oscillator, we can use the following formula:
f = 1 / (2πRC√6)
Substituting the given values, we get:
f = 1 / (2π * 18kΩ * √6 * 1500pF)
f = 1 / (2π * 18 * 10^3 * √6 * 1.5 * 10^-9)
f = 1 / (2π * 16.09 * 10^3)
f ≈ 1.01 kHz
Wien Bridge Oscillator
To calculate the operating frequency of the Wien bridge oscillator, we can use the following formula:
f = 1 / (2πRC√3)
Substituting the given values, we get:
f = 1 / (2π * 10kΩ * √3 * 2400pF)
f = 1 / (2π * 10 * 10^3 * √3 * 2.4 * 10^-9)
f = 1 / (2π * 13.86 * 10^3)
f ≈ 1.14 kHz
Explanation
The BJT phase shift oscillator and Wien bridge oscillator are both types of RC oscillators. These types of oscillators rely on the charging and discharging of a capacitor through a resistor to produce a periodic waveform.
In the BJT phase shift oscillator, the RC network is combined with a BJT amplifier to provide positive feedback. The feedback signal is shifted in phase by the RC network, causing the amplifier to oscillate at a specific frequency.
In the Wien bridge oscillator, the RC network is configured in a bridge configuration with an amplifier. The bridge is balanced at the desired frequency, causing the amplifier to provide positive feedback and oscillate.
The operating frequency of both oscillators is determined by the values of the resistor and capacitor in the RC network. The formulas used to calculate the frequency take into account the phase shift and feedback gain of the oscillator circuit.
BJT Phase Shift Oscillator
- R = 6 kΩ
- C = 1500 pF
- RC = 18 kΩ
To calculate the operating frequency of the BJT phase shift oscillator, we can use the following formula:
f = 1 / (2πRC√6)
Substituting the given values, we get:
f = 1 / (2π * 18kΩ * √6 * 1500pF)
f = 1 / (2π * 18 * 10^3 * √6 * 1.5 * 10^-9)
f = 1 / (2π * 16.09 * 10^3)
f ≈ 1.01 kHz
Wien Bridge Oscillator
- R = 10 kΩ
- C = 2400 pF
To calculate the operating frequency of the Wien bridge oscillator, we can use the following formula:
f = 1 / (2πRC√3)
Substituting the given values, we get:
f = 1 / (2π * 10kΩ * √3 * 2400pF)
f = 1 / (2π * 10 * 10^3 * √3 * 2.4 * 10^-9)
f = 1 / (2π * 13.86 * 10^3)
f ≈ 1.14 kHz
