cascode amplifier मीनिंग इन हिंदी

The CS CG combination is called a cascode amplifier.
Because the input impedance of the common-gate amplifier is very low, the cascode amplifier often is used instead.
A practical solution to this low-input-impedance problem is to place a common emitter stage at the input to form a cascode amplifier.
Figure 1 shows an example of a cascode amplifier with a common source amplifier as the input stage driven by a signal source, " V " in.
