A. None of the mentioned B. △Vio C. △Voo D. △V
Explanation: △V value is the same regardless of whether it is computed from the change in low dc supply or change in +Vcc or -Vee . For example, suppose that -Vee remains constant at -10v then the +Vcc has to vary from 8 to 12v as a result of change in low dc voltage. This means that the change in △V in supply voltage +Vcc is 2v in either direction from 10v. 8. Consider LM307 is initially nulled. Suppose, the op-amp has poor filter, 20mVrms then ac ripple is measured across the terminals. If Vin=0v, determine the change in output offset voltage caused by the change in supply voltage?
