Question

Consider the circuit shown in Fig. 1. The BJT shown has a

\beta =100

and

V_(cc)=10V

. The component values are

R_(1)=100k\Omega ;R_(2)=10k\Omega ;R_(c)=1k\Omega &R_(E)=100\Omega

. The capacitors are large enough to be considered short circuits in the frequency range of operation. Determine (i) the operating point of the BJT; (ii) the voltage gain

A_(v)=(v_(o))/(v_(i))

. (iii) How will the operation of the circuit change if

R_(1)

increases to

220k\Omega

? (iv) Keeping

R_(1)=100k\Omega

, if

R_(2)

is increased to

47k\Omega

, what will be the output of the circuit, if a sinusoidal input of amplitude

50mV

and frequency

1kHz

, is applied? Fig, 1
