(i) Consider a CMOS inverter supplied at VDD= 5V with transistor parameters of KN=KP=50µA/V2 and VTN=-VTP=1V. Then consider another CMOS inverter supplied at VDD= 10V with the same transistor parameters. Draw the VTC of both inverters showing all regions of operation and the middle voltage VM. Verify your results using PSpice.

            (ii) Draw the square root of the CMOS inverter current versus the input voltage for the two CMOS inverters in given in part (i) biased at either VDD=5 V or VDD=10 V. Determine the peak current of the CMOS inverter at VDD=5 V & VDD=10 V. Verify your results using PSpice.

Explain, in your own words and without any detailed circuit analysis, why the CE-CB cascode amplifier extends the upper frequency range of the corresponding CE amplifier.   Your explanation should take no longer than half a page and should cover the following points:

1-

  • Why CE amplifiers tend to have lower 3 dB upper cut-off frequencies compared to CC and CB amplifiers
  • Why the CB amplifier has a higher 3 dB cut-off than the CE
