Formulas for the RC integrator
The integrator works as a pulse shaper stage. The CR element generates a pulse-like alternating voltage at the output of the circuit from a square-wave voltage at the input.
T = Period
t1 = Pulse
If the length of the rectangular pulse (t1) corresponds to 5 times the time constant Τ of the CR circuit, a pulse train like the one in the figure below is created.
\(\displaystyle t1= 5 · R · C\) ⇒ \(\displaystyle R=\frac{t1}{5 · C} \) ⇒ \(\displaystyle C=\frac{t1}{5 · R} \)
If the pulse duration of the input voltage is greater than 5 T, steeper pulses equal to the input voltage are generated
The time constant? (tau)
The time constant of an RC element is the product of R • C. The unit of measurement is the second. The symbol is the Greek letter \(τ \) (tau),
After 5 tau the charge is approx. 99.3%.
