Metastability of CMOS Latch/Flip-Flop
This paper presents several design issues of CMOS latch/flipflops for meta-stable hardness in terms of optimal device size, aspect ratio, and configurations by using the AC small signal analysis in the frequency domain rather than the time domain. This new design approach is verified experimentally. The power supply disturbance and temperature variation effects on the metastability are measured...

flip-flop circuit technique has been designed. CMOS new flip-flop circuit with CMOS domino logic which, All the flip-flops were designed using UMC 180. Recognize standard circuit symbols for D Type flip-flops. though can be largely prevented by using the Edge Triggered D Type flipflop illustrated in Fig 5.3.3. locked loop, using 32 nm CMOS technology. Here we design D flipflop for Phase locked ...
متن کاملSolutions and Application Areas of Flip-Flop Metastability
The state space of every continuous multi-stable system is bound to contain one or more metastable regions where the net attraction to the stable states can be infinitely-small. Flip-flops are among these systems and can take an unbounded amount of time to decide which logic state to settle to once they become metastable. This problematic behavior is often prevented by placing the setup and hol...
متن کاملA CMOS flip-flop featuring embedded Threshold logic functions
This paper describes a semi-dynamic CMOS flip-flop family featuring embedded Threshold Logic functions. First, we describe the new Threshold Logic flipflop concept and circuit operation. Second, we present the concepts of embedded Threshold logic and run-time reprogrammability. Finally, it is proved by Spice simulation results that wide (up to 8 inputs) AND/OR Boolean functions can be embedded ...
متن کاملMetastability of a Flip-flop and Its Utilization for a Capacitance Measurement
Activating a flip-flop circuit by a current fast-rising slope impulse, the circuit occupies one of the two stable states, the stable state ‘one‘ or ‘zero‘. In case of a perfect flip-flop symmetry over a large number of cycles, a noise causes the ratio of ‘ones‘ and ‘ zeros‘ is equal to one – 50% position of a flip-flop. However, any imbalance in the system changes the probability of taking a ‘o...
