Given an inverting amplifier circuit with supply voltage Vcc

Given an inverting amplifier circuit with supply voltage V_cc = plusminus 10 V, R1 = 16 k Ohm, R_i = 200 k Ohm and source resistor R_3 = 6000 Ohm. Answer the following questions Voltage gain? Linear range of the amplifier? What is the swing range of the output signal, if the swing range of input signal is -200mVS V, lessthanorequalto 600mVP (Tip: It is an inverting amplifier.) Will the output signal V0 be dipped, if the input is a sinusoidal signal V_0(t)=cos(50000t +pi/3) (V)? In the following non-inverting amplifier, supply voltage V_cc = plusminus 15V, R1=11K Ohm. R_i= 180K Ohm. and source resistor R_3=60K Ohm Answer the following questions: Voltage gain? linear range of the amplifier? What is the swing range of the output signal, if the swing range of input signal is -900 m V lessthanorequalto v_lessthanorequalto 500 mV?

Solution

a)

For invering amplifier The voltage gain is =-Rf/Rin

here Rin=Rs+R1=16K+600=16.6k

Rf=R2=200Kohm

A=200K/16.6K=12.05

b)

the linear range of amplification is -10V to 10v

c)The swing range of output signal is

-7.5V to 2.4v

5)

a) For non inverting amplifier gain A=(1+Rf/Rin)

here Rin=R1,Rf=R2

A=1+180k/11k=17.36

b)linear range of amplification is -15v to15v

c)swing range will be -15 to 8.68 v
