Explain, in your own words and without any detailed circuitanalysis, why the CE-CB cascode amplifier extends the upperfrequency range of the corresponding CE amplifier.  Your explanation should take no longer than half a pageand should cover the following points:
1-
- Why CE amplifiers tend to have lower 3 dB upper cut-offfrequencies compared to CC and CB amplifiers
- Why the CB amplifier has a higher 3 dB cut-off than the CE
