Flip-flop and Latch : Internal structures and Functions

The flip flop is the most commonly used sequential element in any ASIC design, especially the D-type flip-flop. In the D flip flop, the D indicates delay, which means the output is a delayed version of input D.  Whereas a latch is the simplest and a basic sequential element. In general, there are two latches … Read more

Integrated Clock Gating (ICG) Cell in VLSI

 Low power ASIC design is the need of the hour, especially for hand-held electronics gadgets. In all hand-held products, the customer demands more battery life. This could be possible only if our SoC (System on Chip) inside the gadget consumes lesser power. There are various low-power design techniques that are being implemented the reduce the … Read more
