Higher Critical Frequency Calculation in a Circuit

What are the values of FH(in) and FH(out) based on the given information?

Calculate the higher critical frequency due to the input and output circuit based on the provided data.

Answer:

The values of FH(in) and FH(out) based on the given information are approximately FH(in) ≈ 1.62 MHz and FH(out) ≈ 60.3 MHz.

To find the values of FH(in) and FH(out) in a circuit, we can use specific formulas. FH(in) is calculated using (B / 2π) * √(Cbe * Cbc) and FH(out) is calculated using (B / 2π) * √(Cbc / Cbe).

Given values:

B = 125

Cbe = 20 pF

Cbc = 2.4 pF

Let's calculate FH(in) first:

FH(in) = (125 / (2 * 3.14)) * √(20 * 2.4)

FH(in) ≈ 1.62 MHz

Now, let's calculate FH(out):

FH(out) = (125 / (2 * 3.14)) * √(2.4 / 20)

FH(out) ≈ 60.3 MHz

Therefore, the values of FH(in) and FH(out) based on the given information are approximately:

FH(in) ≈ 1.62 MHz

FH(out) ≈ 60.3 MHz

Higher critical frequency plays a crucial role in circuit analysis and design. It determines the maximum frequency a system can handle before distortion occurs. Understanding these values helps in optimizing circuit performance.
