This article details the design of class E power amplifier.

This article features calculators of:

• Simple calculator
• Resonating frequency.
• Impedance conversion.
• Transmission line RLGC parameters from S parameters.

This paper explains how to implemented distributed components (e.g., transmission line, balun, coupler) with lumped elements.

Analysis in this section will derive S parameters directly.

This article presents S, Z, Y, ABCD parameters and their transformation.

This article will cover

• Calculation of Z and Y parameters of coupled transmission line.
• Different configuration of the coupled transmission line used as two-port network.
• Conversion between the standard S parameter and the mixed-mode S parameter.

This article is about the math typesetting using Latex.

This article will present:

• Identities
• Derivative formulas
• Integral formulas
• Taylor series
• Fourier transformation (include DTFT and DFT)
• Laplace transformation
• Z transformation

This article intends to introduce the basic concepts of current mirrors and the bandgap reference.

This article intends to deal with the analysis of feedback systems.
