Design an Inverter and Oscillator using CADENCE

  1. Design an inverter to get NMH=NML and VM = VDD/2. Draw the layout of the designed inverter.
  2. Obtain the noise margins and the propagation delay time by simulating the layoutand plotting dynamic and static characteristics.
  3. Design an oscillator by placing 5 inverters designed above in a closed loop.
  4. Run a simulation and plot the waveform at the output of each node. Compare the frequency of the generated signal with the expected frequency based upon the obtained tp of the inverter.
