5.8b, where the biasing resistors R1 and R2 have been neglected as they are usually much larger than the input resistance r, of the following amplifier (we can always include them by considering the parallel combination R1∥ R2∥ ri). The midband gain (the C's have negligible reactance (...
The capacitive reactance XC is proportional to 1/C so V2/VS = C1/(C1 + C2) is similar to the formula for the resistor divider. For the simple case where R1 = R2 we have a divider ratio of ½ for the resistors. To have the same ½ divider ratio for the capacitors, then C1 ...

As the capacitance C per unit axial length l is C/l = 2πε/ ln (r2/r1), where r1 and r2 are the radii of the inner and outer cylinders respectively, even with the optimum ratio r2/r1 = e this capacitance is about 56 pF/m and thus large enough to achieve adequate capacitance ...
In this structure, the load circuit 3 includes load resistors R1 and R2 connected between the power supply Vcc and the transistors Q2 and Q3, respectively. The notch circuit 4 includes two LC series resonance circuits connected in parallel to the load resistors R1 and R2, respectively. The LC...

The formula for calculating the expected output voltage is in Equation 3. VOUT = VCC × f × C1 × R1. (3) The sizes of R1 and C1 have other effects on the system such as maximum frequency and output linearity. See Choosing R1 and C1 for detailed instructions on sizing components. ...
Resistors in Parallel: Rt =1/(1/R1 + 1/R2 + 1/R3 ...1/Rn) As an example, assume Rt is 300 ohms. Step 3 Calculate the total inductance of the circuit, or Lt. Lt depends on the number of inductors and how they are connected. If only one inductor exist, Lt is the value of ...
