Ans: Clock generation

Suppose u want to generate a clock from XOR and Delay cell, The XOR and delay cell are not common for all Technologies and Processes.

Even If u do it by full custom design it may not work properly.
The rise and fall delays are different for normal cells (except clock buffers).

So U may not get desired pulse widths and Slew rates..

Hi, Satya,
Would you like to explain your topic in more detail? I think that we can use the inverter to generate a clock signal. And the frequence of the clock is determined by the switching speed of the inverter. Is my understanding wrong? Or maybe there are other consideration when implementing the clock signal in practice?
