I am want to vary the duty cycle for a buck converter analysis. I am using 'vpulse' source for a fixed duty cycle pulse source. Is there any other way to vary the duty cycle in "vpulse source" in Cadence? I know that one can change the duty cycle by using parameter sweep by defining "pulse width" as a variable. What are other easier ways for the same?
Ali Zeki Thanks for your answer. Yes, I want to change the duty cycle continuously in the time domain.
Yes, I know the PWM circuit is one of the possible options to generate the pulse modulating signal. But, I just want to know, is there any direct source or option available in Cadence by which I can vary the duty cycle?
Also, I can vary the duty cycle by the following alternative approaches:
1. First crude way to vary the duty cycle is to use a 'pwl' source, but it is very timeconsuming time-consuming.
2. The other options import the modulated signal from the MATLAB (using a code once can generate pulse-modulated signal).
Hello Vijender Kumar Sharma ,
Yes, using pwl could be another option, as you mentioned. That idea did not come to my mind. However, as you said, it may require an endless effort to create the signal, depending on how you want the duty cycle to change in time continuously. A smooth change will be very difficult to obtain.
Unfortunately, I cannot think of other options which don't require a circuit to create the signal available for continuous modification in time.
Best regards...
