Hello
I am simulating one OP-amp. the op-amp should perform with temperature range from -25 to 80 Co.
I have found at some corners in the worst case analyse that the offset voltage is changing hardly with T so the gain is being killed, while it is stables at the other corners.
I dont know whether I should consider the design is failed or not ?? ??. some friends told me that it is ok to have offset voltage changing high with T but I am thinking then what is the meaning of this test with T?.
Note: the test is performed under open loop condition
I am also looking for your opinions
Thank you very much
