Dear team,
For the high speed comparator, I am curious about these two question:
1. As for the comparator, actually it is the open loop amplifier inside the chip. So is the toggle frequency the GBW of the amplifier? if not, which spec can reflect the small signal bandwidth of this open loop amplifier?
2. is there any specific AC results can evaluate the consequences if the frequency of input small siganl is larger than the toggle frequency. For example, the THD will be fallen to XX dB, the phrase margin will be decreased to XX degree?
Best regards
Wesley Huang
