Hi,
I need to simulate the performance of Envelope Tracking DC-DC converter with PA as shown in figure below. The problem is envelope signal varies quite slowly(MHz) and RF input to the PA input is in GHz. This means that i have to run transient simulation for very long time but with very short time step. It will consume huge amount of time. I read somewhere that envelope simulation in cadence spectre will be useful in these kind of cases. Can some body suggest how can i use envelope simulations for the following circuit.
My input RF frequency =2.4GHz
Envelope signal for DC-DC converter =20MHz
Clock for DC-DC converter =200MHz
