* Question
| The basic structure, main parameters and ideal characteristics of the amplifier? |
* Answer
| Answer: 1. Basic structure: input stage, intermediate stage, output stage, bias circuit 2. Main parameters: 1) open loop voltage gain 2) input resistance 3) output resistance 4) common mode rejection ratio: open loop differential mode amplificationThe ratio of the multiple to the open-loop common-mode amplification factor. 5) Input offset voltage: To ensure that the output voltage is zero,The arithmetic mean of the static base current at both ends of the amplifier 10) Maximum common mode input voltage 11) Maximum differential mode input voltage 12) Rated output voltage 13) Static power consumption: When no load is connected and there is no input signal, |
