Clock dividers are ubiquitous circuits used in every digital design. A divide-by-N divider produces a clock that is N times lesser frequen...

A time to digital converter is a circuit that digitizes time; i.e., it converts time into digital number. In other words, a time-to-digita...

‘X’ refers to a signal attaining a value that is ‘unknown’. It can be either ‘0’ or ‘1’. But, the exact value of the signal is not known...

Static timing analysis of a design is performed to estimate its working frequency after the design has been fabricated. Nominal delays of ...

Performance of the system is one of the most stringent criteria for its success. While performance increases the desirability among custo...

LBIST stands for Logic Built-In Self Test. As VLSI marches to deep sub-micron technologies, LBIST is gaining importance due to the unique ...

Worst slew propagation is a phenomenon in Static Timing Analysis. According to it, the worst of the slews at the input pin of a gate is p...

As we know, depletion MOSFET conducts current even with gate and source at same voltage level. To cut-off the current in depletion MOSFE...

In the post ( Setup and hold – basics of timinganalysis ), we introduced setup and hold timing requirements and also discussed why the...
