the common-collector configuration gives the benefits of a high input resistance, low output resistance, and a high current gain. The combination of high input resistance and low output resistance allows a common-collector amplifier to function as a buffer that keeps loading effects low if the cir...
In this article I will show a method to deduce the input and output resistance of the common collector amplifier. The common-collector amplifier is a well known circuit (see Figure 1). It is mostly used as a buffer due to its high input resistance, small output resistance and unity gain....
The current gain of the CB circuit is calculated in a method related to that of the CE concept and it is denoted with alpha (α). It is the relationship between collector current and emitter current.The current gain is calculated by using the following formula. Alpha is the relationship of...
A basic BJT common emitter amplifier has a very high gain that may vary widely from one transistor to the next. The gain is a strong function of both temperature and bias current, and so the actual gain is somewhat unpredictable. One common way of alleviating these issues is with the use...

The similar supply voltage also decides the utmost collector current, as the transistor is activated that is in saturation mode. Common Emitter Voltage Gain Common emitter voltage gain is equivalent to the modification within the input voltage ratio to the modification within the amplifier o/p voltag...
The present system in particular is against human nature, or what is the policeman for, the soldier, the debt-collector, the judge, the hangman? What means the glass along my neighbour’s wall? Human nature is against human nature. For human nature is in a perpetual conflict; it is the...
In this circuit the base terminal of the transistor is the input, the collector is the output, and the emitter is common to both and hence its name.The simple common emitter amplifier gives the amplifier an inverted output and have a high gain that may vary widely from one transistor to ...
