A center-tapped rectifier is a type of full-wave rectifier that uses two diodes connected to the secondary of a center-tapped transformer, as shown in Figure (a).
Opto coupler are designed to provide complete electrical isolation between an input and output circuits.
The operational amplifier or OP-AMP is a direct coupled, high gain amplifier used to perform a wide variety of mathematical operation used to perform like summation, subtraction, multiplication, di
EFFECT OF BIAS CURRENT
Transistor’s within the OP-AMP must be biased so that have the current values of base and collector current and collector to emitter voltages.
The operational amplifier is direct-coupled high gain differential amplifier.
A inverting amplifier provides the same function as the common emitter and common-source amplifiers.
How transistor, capacitor, resistor and diodes are fabricated on a chip.
The separately manufactured components like resistor, capacitor, diode, and transistor are joined by wires or by printed circuit board (PCB) to form circuits.
The hybrid parameters are generally used to determine amplifier characteristic parameters such as voltage gain, input and output resistance etc.
Figure(a) shows a transistor amplifier circuit.
The figure shows the transistor connected in common emitter configuration and the figure also shows the hybrid equivalent circuit of such a transistor.
