Phase Shift Oscillator Circuit explanation using op-amp, transistor and FET

Phase shift oscillator is an RC type oscillator whose output is fed back to its input through a phase shift network consisting of resistors and capacitors in a ladder network. In our last tutorials, we explain LC oscillator like Hartley, Colpitts etc, Wien bridge oscillator and crystal oscillator in detail. Here we are going to explain Phase shift oscillator and its implementations in detail. For required positive feedback in RC oscillator, the input is shifted 180o through the amplifier stage and another 180o through the inverting stage which gets combine and gave a phase shift of either 360o or 0o …

MOSFET Transistor: Easiest Basics, Operation and Types

Transistors are a widely used component in an electrical circuit. We have already discussed FET (Field effect transistors) and JFET (Junction Gate Field-effect transistors) in our previous tutorials. Another most used Transistor is Mosfet. In this tutorial, we will explain its definition, working modes, operation,  and types. What is Mosfet: Definition and explanation According to Wikipedia The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon.  It has an insulated gate, whose voltage determines the conductivity of the device Let’s understand this definition of Mosfet …

JFET Transistor: Operation and Characteristics

JFET is the first form of field effect transistor to be developed can be used as a voltage controlled resistance or as an electronically controlled switch. In our previous articles, we explain in detail about Field Effect Transistor operation and comparison between Jfet & Mosfet. In this, we are going to explain you in detail about Jfet operation and biasing. Junction Field Effect Transistor: JFET consist of the channel of semiconducting material through which a current flows. Jfet’s are of two types; one is n-channel JFET and another is p-channel JFET. Generally, n-channel JFET are more preferred than p-channel JFET because …

Field Effect Transistor: Operation and Types

The field effect transistor is a three terminal unipolar semiconductor device used for weak signal amplification. This type of transistor basically uses an electric field to control the shape and hence the electrical conductivity of a channel of one type of charge carrier in a semiconductor material. FET has various similar characteristics to those of their bipolar transistor counterparts i.e. robust, cheap, high efficiency and instant operation and can be used in various electronic circuit applications. In our previous article, we explain the difference between BJT and FET, Semiconductors electronics Theory. Here we are going to explain FET operation and its …
