Simple single transistor audio amplifier

Single Transistor Amplifier

This is an interesting practical project which even a novice can build! It is a simple single transistor amplifier circuit which can be powered by 1.5V to 5V. This project uses few components which you can easily get even from a dead circuit. The circuit uses a single NPN bipolar junction transistor (BJT) and can drive

Transistor acting as a switch

Transistor acting as a switch

Probably you might have heard someone said that a transistor is use as a switch or signal amplifier and you thought how? Don’t worry; you have come to where you will get the answer of the “how?” This article “transistor acting as a switch” will explain and show you how transistor is use as an

BJT ACTIVE REGION

BJT active region

In this post, you will learn about bipolar junction transistor (BJT) active region. Also after this, links for the other two operation regions are provided immediately. ACTIVE REGION In active region the transistor is bias so that the base (B) measures a higher potential difference (Pd) to the emitter (E) but lower than the collector

BJT SATURATION REGION

BJT saturation region

We will be talking about bipolar junction transistor (BJT) saturation region (FULLY ON) in this post. Also, Links for the other two operation regions are provided immediately. SATURATION REGION (FULLY ON) A transistor is said to be saturated (Fully ON) when it is biased in such a way that current passes from the Emitter (E)

BJT CUTOFF REGION

BJT Cutoff region

This article is centre at Bipolar Junction Transistor (BJT) cutoff region or FULLY OFF region. CUTOFF REGION (FULLY OFF) In Bipolar Junction Transistor (BJT) cut off region or fully off region, the transistor is bias in such a way that both junctions are reverse so that no current will pass from the emitter (E) to

BJT operating regions

When we talk about Bipolar Junction Transistor BJT operating regions, we mean ways in which Bipolar Junction Transistor is use. Bipolar Junction Transistor (BJT) has basically three (3) operating regions. These are; Cut off region (FULLY OFF) Saturation region (FULLY ON) Active region. CUTOFF REGION (FULLY OFF) In cut off or fully off region, the
