Unformatted text preview: Problem 0.6 Souk-m The Gig—amp used in the circuits in this problem has a very largtt Opemloop gain, very large input resistance, railuto-rail input common—mode voltage range and rail-to~.rai1 output voltage swing. a) When the 0p~amp is connected. as shown in Figure 1(a), the DC output voltage: is found to be V0 7» 10 mV. What is the input offsat voltage V05 ofthe 0p~amp?
