1. What Is The 3 DB Frequency Of CS Amplifier Without Dominant Poles?

The 3-dB frequency of a CS (Common Source) amplifier without dominant poles represents the frequency at which the signal power is reduced by half (3 decibels) from its maximum value. It is a critical parameter in amplifier design that determines the bandwidth and frequency response characteristics.

2. How Does The Calculator Work?

The calculator uses the formula:

\[ f_L = \sqrt{\omega_{p1}^2 + f_P^2 + \omega_{p3}^2 - (2 \times f^2)} \]

Where:

\( \omega_{p1} \) — Pole Frequency 1 (Hertz)
\( f_P \) — Frequency Of Dominant Pole (Hertz)
\( \omega_{p3} \) — Pole Frequency 3 (Hertz)
\( f \) — Frequency (Hertz)

Explanation: This formula calculates the 3-dB frequency by considering the combined effect of multiple pole frequencies in the amplifier circuit, providing an accurate estimation of the frequency response cutoff point.

3. Importance Of 3-dB Frequency Calculation

Details: Accurate 3-dB frequency calculation is essential for amplifier design, signal processing applications, and ensuring proper frequency response in electronic circuits. It helps determine the usable bandwidth and performance characteristics of amplifier systems.

4. Using The Calculator

Tips: Enter all frequency values in Hertz. Ensure all values are non-negative and valid for accurate calculation results.
