This calculator determines the amplifier gain in the mid-band frequency range using the complex frequency variable approach. It accounts for various frequency parameters including 3 dB frequency, observed frequency, and pole frequencies to calculate the precise gain value.
The calculator uses the following formula:
Where:
Explanation: The formula calculates the square root of the ratio between the product of terms involving the 3 dB frequency with frequency and observed frequency, and the product of terms involving the 3 dB frequency with pole frequencies.
Details: Accurate amplifier gain calculation is crucial for designing and analyzing electronic circuits, particularly in high-frequency applications where signal integrity and amplification characteristics are critical for system performance.
Tips: Enter all frequency values in Hertz (Hz). All values must be positive numbers greater than zero. The calculator will compute the amplifier gain in the mid-band frequency range based on the provided parameters.
Q1: What is 3 dB frequency?
A: 3 dB frequency is the point at which the signal power is reduced to half (approximately 70.7% of the maximum amplitude) in frequency response characteristics.
Q2: What are pole frequencies?
A: Pole frequencies are specific frequencies in a system's transfer function where the response approaches infinity, representing critical points in the frequency response.
Q3: Why is mid-band gain important?
A: Mid-band gain represents the stable amplification region where the gain is relatively constant and unaffected by low or high-frequency roll-off, making it crucial for signal processing applications.
Q4: Can this calculator be used for audio amplifiers?
A: Yes, this calculator can be used for various types of amplifiers including audio amplifiers, provided the frequency parameters are within the appropriate range for the specific application.
Q5: What units should I use for frequency inputs?
A: All frequency values should be entered in Hertz (Hz). For higher frequencies, you may use kilohertz (kHz) or megahertz (MHz) by converting to Hz (e.g., 1 kHz = 1000 Hz).
