Hi,
I am trying to understand how the Colpitts oscillator works. From Razavi's book, it is indicated that the minimum required gain should satisfy the requirement of gmRp > 4 (Chapter 15.3.3, Eq15.46). Further, there are ideas that the circuit oscillate when the transfer funtion becomes...
Hi there,
I am learning how to make integrated circuit design in Cadence, and starting with an inverter. For the layout design, I noticed that someone aligns the pins(Vin, Vout, Vdd, Vss, etc.) to the metal layer while someone aligns them to the poly layer. Which one is correct? What is the...
Thanks so much for your reply!
I have run some simulations and found out it was the physical structure of the coil that made the circuit mismatched. I have followed your suggestions and found suitable LC parameters.
Hi, I am doing a simulation about the WPT coil and have a problem with impedance matching circuit simulation in HFSS. I set the frequency to be 13.56MHz and generated an impedance matching circuit in ADS based on the impedance of the coil, and the result seemed valid in ADS. However, when I...
