Yeah, but that uses transistors.

Something like this?

hi all,
I want to know the advantages of edge triggered flip flop over master-
slave flip flop.
Please let me know this.
thanks in advance.

Except an "edge-triggered" flip-flop IS "master-slave".

Huh? Please post a schematic of an edge-triggered flip-flop. I'll
make it easy on you... you are allowed to use a PECL/ECL configuration
;-)

John Larkin said:No. Not all edge-triggered flipflops have the master-slave
architecture. And not all master-slave flops are edge-triggered; one
could design a m/s level-sensitive transparent latch.
Master-slave is an internal architecture. D, T, JK, RS,
level-sensitive, edge triggered, are all external behaviors.
The DDR flops in Xilinx io blocks are interesting; they have two
edge-sensitive clocks. That must be interesting to implement; it can't
be classic master/slave.
I used to design flipflops that used only resistors, capacitors, and
diodes.

Delighted!
Hopefully Al Franken's candidacy will be damaged.
Why? I thought he was running for 'The biggest idiot on earth'?
Yes... but only in Minnesota...
