thanks!
but i dont understand what you mean by skipping initial operating point calculation.. how does that trigger the comparator?
and in this circuit the frequency of the oscillator is determined by the integrator isnt it? so when you do a time domain analysis on the integrator circuit you get
Code:
Voc = 1/RC × ∫Vin dt
= 1/RC × Vin×t
so if i want a frequency of 5kHz and the C value is 10 nF and the output signal is supposed to be 5V(p-p)
i substitute
Voc = 5, C = 10nF , Vin = 15 , t = 1/2f
but the R value im getting is twice the actual value
what am i doing wrong?
