Find upsilon_o for the circuit in Figure P8.7.

Since this is an inverting amplifier, Gain=-R(f)/R(in) (-) implies negative feedback

R(f)=12k , given,

R(in) =(2k||4k)+6k=(8/6)k +(6)k=(22/3) k ; 2||4=(2*4)/2+4

Gain=Vo/Vin=-R(f)/R(in)

hence,

solving this,

Vo/11= -12/(22/3)

Vo/11= -36/22

Vo=-18V i.e 18V with phase shift of 90 degrees.
