Microelectronics and integrated circuits present the backbone of modern civilization. The input of the frequency divider is a square wave with a nominal frequency of 32 kHz, and it outputs a square wave signal having the frequency of 1 Hz. The operation of an integrated circuit can be influenced by temperature and technological imperfections in production, which results in the deviation of the input frequency from the nominal frequency of 32 kHz. It is necessary to create the possibility to tune the frequency divider to get the output frequency of 1 Hz. The frequency divider consists of a 15-bit synchronous counter with reset, 15-bit adder which adds the 15-bit constant C0 and the 8-bit vector FDT, and a 15-bit comparator that generates the reset signal when these two numbers are equal. The constant C0 and tuneable vector FDT have to be set to generate the frequency of 1 Hz even if the temperature varies from -40 degrees Celsius to 125 degrees Celsius and if the voltage supply varies from 1.1 V to 1.3 V. With the nominal power supply voltage of 1.2 V the circuit is allowed to consume up to 100 nA. Run the simulations for corner technologies and determine appropriate values for C0 and the 8-bit vector FDT. Assure that the circuit works correctly when the external signal EN is high and if the signal EN = 0, then the circuit is not allowed to work. Describe the process of designing the circuit. All important circuit characteristics have to be represented in graphical and tabular form.
