Ok im working through question p6.109 of sedra smith part b. And im using the fact that Gv=10/10=vo/vsig to try and solve for Rd. My lecturer says the formular for vo= -gm.vsg.Rd. but i just cannot find it using kvl. Its negative because its 180 dregrees out of phase but i cannot kvl in my pie modle of the circuit to get the result. Also im confused on the effect the cappacitors have in regards to Rs when in ac analysis.
The last image shows my pie model but with all the earths connected. The the kvl entering at vo leaving through the earth.
Any help would be great. Cheers
