Two Transistor Amplifier


For most systems single nbsp transistor amplifier does not provide sufficient gain or output impedance matching The solution is only to combine multiple stages of amplification In this amplifier circuit we are going to show a simple two-transistor amplifier In the single-transistor amplifier circuit we have made a very simple amplifier with one transistor one resistor and one capacitor but the amplifier has been designed with two transistors We have designed this amplifier by using two transistors including PNP and NPN transistors and we adopted the overall topology of the Sziklai pair The two-transistor amplifier provides a reasonably high impedance Read More

Single Transistor Amplifier Circuit


This article is about Single Transistor Amplifier Circuits nbsp An audio amplifier is a device that multiplies an applied input signal amplitude to a level that may be much higher than the input signal The input is given in the form of audio or music The amplifiers are classified into classes like class A class B class AB class C and class D Here we are going to discuss the first type of amplifier i e class A amplifier and also learn how to build a single transistor amplifier circuit class A Amplifiers are generally very efficient because these amplifiers Read More

Simple Uninterruptible Power Supply (UPS) Circuits


In this article we are going to instigate a simple Uninterruptible power supply UPS using a V battery We are going to explain these UPS circuits very simply so that a new electronics student can understand These UPS circuits can be used for operating a specific appliance or load Simple Uninterruptible Power Supply In this circuit idea we can build at home using the most ordinary or commonly used components to produce a reasonable output This simple UPS circuit can be used not only for the usual electrical load but also in complex gadgets like computer supplies This inverter circuit Read More

Fire Alarm Circuit using Transistor


In this amazing article we are going to make a fire alarm circuit A Fire Alarm System is a device that makes a loud sound to warn people when there is a fire In this project we have designed a Simple and inexpensive fire alarm circuit by using a transistor BC and an IR receiver sensor This Fire circuit alert through a buzzer sound whenever any kind of fire is detected in the air or an environment It can detect any kind of fire such as radiation heat etc Depending on the type of sensor that matches an application is Read More
