Common emitter non-symmetrical gain – I have simulated in LTspice a very simple CE amplifier. There is no AC capacitor at the emitter It is a plain and simple CE emitter bias unbypassed with a gain of Av = -Rc / RE = 4.07. It turns out that, as input is a perfect 1V sine […]

Why is unloaded buffer showing an offset? – I am using an AD8041 IC as a buffer for a 0.2 Vpp sinewave input at 1 kHz from the function generator. The circuit is set on an NI Elvis II+ board. The buffer is unloaded but there occurs some offset at the output of the buffer. […]

Amplifying DC voltage from 5V to 12V – I use an Arduino board with a 5V output supply but I Ineed to operate 12V motor. I know that I could connect the Arduino to a 12V power supply to solve the problem. But but I can’t do it for some of reason so I have to build […]
