1)
One of the important criteria to have oscillations in a ring oscillator is
Even number of inverter stages
Odd number of inverter stages
Does not depend on the number of inverter stages
2)
For an N-inverter chain ring oscillator with frequency of oscillation 'f', the propagation delay of the gate will be
N*f
2N*f
1/(N*f)
1/(2N*f)
3)
The oscillation in a ring oscillator is ensured when
The number of inverter stages are larger
The rise time is larger
The fall time is larger
The delay of each inverter is smaller
4)
To increase the frequency of oscillation, which of the following can be utilized? (a) Applied power supply voltage may be increased. (b) Reduce the number of inverter stages.
(a) only
(b) only
both (a) and (b)
neither (a) nor (b)
5)
How the frequency of oscillation affected by the increase in temperature of a ring oscillator?
frequency increases with increase in temperature
frequency decreases with increase in temperature
frequency remains the same
frequency increases first and then decreases
