For the multivibrator shown in Fig. 7.13(a), VCC = 20 V, VBB = 10 V, R1 = R2 = R = 10 kΩ, C1 = C2 = C = 0.01μF. Find the time period and the frequency.

Question

For the multivibrator shown in Fig. 7.13(a),[latex]\ V_{CC}[/latex] = 20 V,[latex]\ V_{BB}[/latex] = 10 V,[latex]\ R_{1} = R_{2} = R[/latex] = 10 kΩ,[latex]\ C_{1} = C_{2} = C[/latex] = 0.01μF. Find the time period and the frequency.

Accepted Answer

[latex]\ T = 2RC ln \left(1 + \frac{V_{CC}}{V_{BB} } \right) = 2 × 10 × 10^{3} × 0.01 × 10^{−6} ln \left(1 + \frac{20}{10} \right)[/latex] = 0.22 ms

[latex]\ f = \frac{1}{T} = \frac{ 10^{3}}{0.22}[/latex] = 4.54 kHz
