I'm trying to use the active inductor in here instead of the inductor in my class e power amplifier, however I'm having difficulties in getting the required values for the parameters in here Cds, Cgs, Cgd and Ceq for example. I have the spice model for the components in the library that I'm using inside of Cadence Virtuoso.

enter image description hereenter image description here

The article in the screenshots: https://www.researchgate.net/publication/338188528_A_29-dBm_OIP3_Dual-Stage_Power_Amplifier_with_Analog_Pre-Distorter_in_018_m_CMOS_for_IoT_Transceiver

  • \$\begingroup\$ Edit: I apologize Ceq is already known from the article which is Ceq = C4 +C5 + Cgs3 + Cgs4 \$\endgroup\$

  • \$\begingroup\$ I don't know how Cadence-Pspice does it, but I know in LTspice if you run an .op analysis under your desired DC conditions you can view the small-signal "linearized" parameters for Cgs Cgd etc. by looking at the SPICE Error Log (CTRL+L). Regardless, it'll depend on the specific model/subcircuit you're using for the PMOS transistors. \$\endgroup\$
