StevenIC: Tips 'n Lifehacks of Design of Analog IC, Mixed-Signal IC (AMS) & RFIC (©Steven)

[Welcome to citing and linking to the pages of this blog] Summary of learning and practice of analog circuit, mixed-signal circuit and RF circuit designs, focused on their integrated circuit (IC) implementations. General knowledge learned from books, papers and practices are summarized. This blog also holds Job Hunting Guide, including interview questions, written by Fuding Ge.

Free IC design and simulation tool: Qucs, Quite Universal Circuit Simulator

http://en.wikipedia.org/wiki/Quite_Universal_Circuit_Simulator

http://qucs.sourceforge.net

"It gives you the possibility to set up a circuit with a graphical user interface and simulate the large-signal, small-signal and noise behaviour of the circuit."

"Pure digital simulations are also supported using VHDL and/or Verilog."

"Analysis Types:
S-parameter, including noise
AC, including noise
DC
Transient Analysis
Harmonic Balance (not yet finished)
Digital simulation: VHDL as well as Verilog-HDL
Parameter sweeps"

Question:

Where to find model parameters for transistors?
