# Common Emitter Amplifier Design Page

Supply Voltage Vs = V (dimensionless) mA (Note 1) (dimensionless) (Note 2) V (Note 3)

Note 1: A good starting point for small signal amplifiers might be 2mA.

Note 2: For the base voltage to be held firmly at low frequencies, this value should be 10.

Note 3: For silicon transistors this is generally assumed to be 0.7 Volts.
