Hello all,
I have designed a Cherry Hooper amplifer with emitter feedback for my thesis. I am gettign a little bit of deviations betw. 38KHz and 2.5 MHz for a frequency range of 100Hz to 300GHz (I am working on higher frequency range). I don't know why there is such a descrepancy. I need a steady voltage output till say 1 GHz and then tje voltage has to gradually decrease. It would be helpful for me if anyone let me know where the error is. I need to caclulate the voltage output from 100Hz to 300GHz. I have maintained the common mode voltage at 3.1V. A quick reply would be really helpful. I have attached the simulation graph along with this post. Thanks in advance.
