For this circuit, if i try to amke the oscillator operate at 20kHz and the output swing btw +/-5V where the output current i want to be below 100mA with the resistor value >1MOhms is undesirable. How can i calculate:
i). Ri and C1?
ii). minimun working voltageof capacitor
iii).ratio of R1 to R2 to make the comparator swing when the v1 is +/-0.5Vcc
Can anyone teach me how to calculate this as this is one of the question in my past exam paper.
