Digital concept
What is the difference between latch and flipflop?what is the main difference between 8085 and 8086 processors?
ubabmar
- Jun 24th, 2009
In Latch & Filpflop the only difference is control signal. i.e Clock Signal The 8085 is a 8bit processor & the 8086 is a 16bit processor. In 8085 we can't do Multiplication or division by using singl...

MOSFET Pinch Off Voltage
In a MOSFET, What does the pinch off voltage refers to?
Sagar21p
- Oct 7th, 2010
Pinch off voltage is the excess voltage Vds applied which limits the current flowing into drain.. at that point the current saturates...and the o/p current remains constant.
kumar praveen bodu
- Mar 23rd, 2010
Pinch-off voltage refers to the maximum gate current applied to MOSFET to increase the depletion layer between source and drain.

1000kHz (input) to a DEMUX with a Select line.1st output connected to D Flipflop (acts as divide by 2) thus 500kHz.2nd output connected to TWO D Flipflops (acts as divide by 4 ) thus 250kHz.
