per correct answers - Amplifier has AV-4001 and Av260018 the overall Avis (b) 20 dB (e) 10001 (d) 50 (c) CCCS (b) Vecs (d) CCVS National Amplifier is: . Ir be mis output voltage at midband is 10 y, then at low cutoff frequency the peak (b) 14.1 (e) 10 v (d) 5v qut voltage is (c) Darlington Amp. (d) Buffer w seade Amp. (b) Cascode Amp. . (e) R, decrease (d) Answer a &c (8) Ay increase (a) 100.05 kHz For a very high current gain, one of the following Amps. is used: 9 In CG amplifier with R. and Rp when R, increases then (b) Ro increase An amplifier has low cutoff frequencies : 500 Hz, 200Hz, and a bandwidth of 99.7kHz, the high cutoff frequency is: (b) 99.9 kHz (c) 100.2kHz (d) 100.4 kHz 7) In midband range of an amplifier: (a) Ce short and Copen (b) Ce open and C short (e) C and Copen (d) C and C short 8) For practical Differentiator when the input is square wave the output is: (b) triangular wave (d) inverted square wave 9) One of the following amplifiers is used as a wide-band amplifier : (a) Cascade Amp. (b) Cascode Amp. (c) Darlington Amp. (d) Buffer (a) rectangular wave (e) impule 10) For high and adjustable differential gain and high input resistance ,use : a) Non-inverting Amp. b) Instrumentation Amp. e) Difference Amp. d) none 11 ) The voltage follower is not similar to : a) C.D Amp b) C.C Amp. c) C.S Amp. d) none. 12 ) The Ay of BJT amplifiers is larger than that of MOSFET Amps. due to : a) low gm value for the same current b) high gm value for the same current c) high Rin for MOSFET Amps. d) Two types of carriers are used
