regeneration time constant of a comparator

regeneration time constant

can somebody explain abt the reset and regeneration time calculation for a comparator using regenerative latch

Thanks

comparator regenerative time

try "Cmos Analog Circuit Design, Phillip Allen" chapter 8
or "Analog Integrated Circuit Design, D Johns"

Both of the books have detail description of time constant calculation.

comparator time constants

the regenerative time constant of the latch is set from the probability of error spec of the latch. This comes because of the
metastability condition. The time constant of the latch will be (gmp + gmn)/Cl where gmp and gmn gm of PMOS and NMOS respectively in back to back inverter configuration and Cl is the output cap load.
For metastability analysis u can refer..

hope this helps
