Second Pole-Frequency of CG Amplifier Solution

Follow our step by step solution on how to calculate Second Pole-Frequency of CG Amplifier?

FIRST Step Consider the formula

f p2 = \frac{1}{2 \cdot π \cdot R L \cdot (C gd + C t)}

Next Step Substitute values of Variables

∴

f p2 = \frac{1}{2 \cdot π \cdot 1.49kΩ \cdot (1.345μF + 2.889μF)}

Next Step Substitute values of Constants

∴

f p2 = \frac{1}{2 \cdot 3.1416 \cdot 1.49kΩ \cdot (1.345μF + 2.889μF)}

Next Step Convert Units

∴

f p2 = \frac{1}{2 \cdot 3.1416 \cdot 1490Ω \cdot (1.3E-6F + 2.9E-6F)}

Next Step Prepare to Evaluate

∴

f p2 = \frac{1}{2 \cdot 3.1416 \cdot 1490 \cdot (1.3E-6 + 2.9E-6)}

Next Step Evaluate

∴

f p2 = 25.2280108758271Hz

LAST Step Rounding Answer

∴

f p2 = 25.228Hz
