C cookas New Member Mar 23, 2010 #1 Hi, I'm new in electronics and I need some help analysing a circuit. I want to determine Vout/Vi but the Rc is confusing me. I need to find the common mode voltage and the differencial mode voltage. I also want to determine Vout/Vi admiting that R doesn´t exists. Thanks Attachments ampop..png 5.9 KB · Views: 148
