Q Explain about 'Darlington Amplifier'?
DARLINGTON AMPLIFIER : A CC stage followed by another CC stage has an input resistance of about (b + 1) 2 times the emitter resistance of the second stage. More precisely, using the b transform, it is
If RE1 is removed, the second term is about b2 times RE2. Furthermore, if the collectors are connected together, the result is a Darlington stage, as shown below.
This stage can be viewed as a "Darlington transistor" because it has three terminals and an equivalent b of about b2 . Darlington BJTs can be used in any of the three BJT configurations.
Explain current divider rule Current flow through at every resistor that connected by parallel can be find by using current divider rules (CDR).
A communication system for a voice-band (3 kHz) channel is designed for a received SNR E b /N 0 at the detector of 30 dB when the transmitter power is Ps =-3 dBW. Find the value o
