Who is the Common-Emitter Amp poster for?

Common-Emitter Amp belongs to the Electrical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning electronics can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Common-Emitter Amp poster?

The first amplifier worth designing by hand, and the template for the ones after it. A wall chart earns its place by being glanceable from where the work is happening, so Common-Emitter Amp belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.

What other posters go with Common-Emitter Amp?

BJT Operating Regions, BJT vs MOSFET and Diode Behaviour sit alongside Common-Emitter Amp in the Electrical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.

Is the Common-Emitter Amp poster free to download and print?

Yes. Common-Emitter Amp downloads as a free PDF with no account, no email and no watermark, like everything else in the Electrical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.

What size does the Common-Emitter Amp poster print at?

Common-Emitter Amp is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Common-Emitter Amp loses nothing.

Common-Emitter Amp, step by step

Bias first, gain second. A stage biased badly cannot be rescued by gain.

Set the quiescent pointAim for V_CE near half the supply so the output can swing both ways.
Choose the emitter resistorOne or two volts across R_E makes the bias immune to β and to heat.
Size the bias dividerDivider current about ten times I_B keeps the base voltage stiff.
Find the gainA_v ≈ −R_C/R_E when degenerated, or −g_m R_C with R_E bypassed.
Add coupling capacitorsEach cap and its resistance set a low corner; place them below the band.

Bypassing R_E buys gain and loses stability: the gain then follows g_m, which moves with bias current and temperature.
