Electronic Circuit Calculation is a free Android application designed to calculate the voltage gain, input and output impedance of the common emitter AC circuits, common emitter without bypass, common collector, common base, common source, common source without bypass, common drain, and common gate using the simplified H model and the FET transconductance model. The app also includes a module for calculating the color code of resistors.

The calculation in AC uses simplified models for small signals, and the DC calculation for BJTs is done using IC = BETA * IB. For FETs, the DC calculation is done using the Shockley equation. With its easy-to-use interface and powerful calculations, Electronic Circuit Calculation is an essential tool for circuit analysis enthusiasts and professionals alike.
