AC analysis of a common-emitter amplifier circuit begins by recognizing the capacitive reactance (XC) remains very low at the signal frequency. By considering XC as equal to zero, reducing the circuit to an ac equivalent circuit requires replacing the three capacitors in the circuit with effective...
The Transistor as an Amplifier The transistor is also what makes amplifiers work. Instead of having just two states (ON/OFF) it can also be anywhere in between “fully on” and “fully off”. That means a small signal with almost no energy can control a transistor to create a much stron...
What is a transistor and its types? A transistor is a semi-conductive electrical device used as a switch, or as an amplifier. The most common types are field effect transistors (FETs) and bipolar junction transistors (BJTs).What is a Transistor? A transistor is a device with an electrical...
I have to analyze an amplifier circuit from a microphone to a speaker and don't understand how it works. I know that the first stage is a voltage divider, but I can't figure out what the second stage is or how it works? In which stage does the amplification take place? I would rea...

Also, the operation of the BJT and FET as amplifiers each in three configurations was discussed. While the methods utilized gave reasonably good answers, more precise design requires the use of BJT and FET models or equivalent circuits. The models we adopt are the hybrid parameter or h-...
Operational amplifier is used as comparator. In this circuit the comparator and the latch is powered from the same power supply. The required power supply to the operational amplifier is derived either from a separate battery or from the ac input it self. In the second case an isolation ...
