I think you're supposed to use buffered inverters, where there is no possibility of stable DC operation.Novice10 said:
A Pspice ring oscillator is an electronic circuit that uses positive feedback to generate a continuous oscillation signal. It is commonly used in the design and testing of integrated circuits.
A Pspice ring oscillator consists of an odd number of inverters connected in a ring, with the output of the last inverter connected to the input of the first. This creates a loop of positive feedback, causing the output signal to oscillate at a specific frequency determined by the time delay of the inverters.
Pspice ring oscillators are used in circuit design to test the performance of integrated circuits, including their speed, power consumption, and noise characteristics. They are also useful for generating clock signals in digital circuits.
The frequency of a Pspice ring oscillator is affected by the number of inverters in the ring, the delay of each inverter, and the supply voltage. Additionally, any external capacitances or resistances connected to the oscillator can also impact its frequency.
To simulate a Pspice ring oscillator in software, you can use Pspice software or any other circuit simulation tool that has a Pspice library. You will need to create a circuit using the appropriate Pspice components and simulate it to observe the oscillator's behavior and frequency.
