As we run simulation of a circuit,we see from spectre or else that with temperature increasing,the performance of the circuit degraded.Like the speed becomes slower. But what the exact reason for this phenomenon? I can imagine two reasons,one is that the mobility is decreasing while temperature increasing, the other is that the R has positive TC so its value becoming large and the RC constant has increased account for speed down. I wonder whether one of my option is right? And what about the influence on the gain with temperature?I think gm is aslo decreaed with mobility reduction,right?
Best regards urian
