Advantages, Disadvantages and Applications of Transformer Coupled Amplifier

Advantages and Disadvantages of Transformer Coupled Amplifiers

Advantages:

1.       No signal power is lost in the collector or base resistors.

2.       An excellent impedance matching and can be achieved in a transformer coupled amplifier.

3.       Due to excellent impedance matching, transformer coupling provides higher gain.

4.       D.C isolation between first and second stages.

Advantages, Disadvantages and Applications of RC Coupled Amplifier

Advantages and disadvantages of RC Coupled Amplifier

Advantages:

1.       The frequency response is excellent.

2.       This circuit is very compact and extremely light.

3.       Cost is low because it employ resistors and capacitors which are cheap.

Advantages, disadvantages and applications of FET over BJT

Advantages, disadvantages and application of FET over BJT

Advantages

1.       FET gas high input impedance of several mega ohms.

2.       The noise produced by a FET is less than that produced by a BJT.

3.       FETs are less effect by radiation compared to BJT.

4.       FET has no offset voltage at zero drain current and hence it forms an excellent signal chopper.

5.       FETs are voltage controlled devices.

6.       FETs have better thermal stability.
