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.
Give the applications of PVC. PVC- It is acquired from polymerisation of hydrogen chloride and acetylene in the presence of a catalyst as peroxides at about 50 0 C. It is e
A symmetrical fluctuating message, with |f(t)| max = 6.3 V and KCR = 3, is to be encoded by using an encoder that employs an 8-bit natural binary code to encode 256 voltage levels
Operation of MOSFET The operation of a metal-oxide-semiconductor field-effect transistor which is abbreviated as MOSFET can be separated into three modes, depending upon the
Q. Define Number Systems? A number system, in general, is an ordered set of symbols (digits) with relationships defined for addition, subtraction, multiplication, and division.
Q. A table for the direct 3-bit binary decoding is given. Show a block diagram for a 3-to-8 decoder and suggest a method for its implementation.
Q. What do you mean by Output Voltage Swing? Ideally this is equal to the difference between the two supply rail voltages, although in practice it is a few volts less.
