Fastest Inverter
Hi,
I am doing a school project which involves designing a 4-bit LFSR (one xor in the front that is fed from the last 2 FF's) using 0.18u in Cadence. The goal is to make it as fast as possible, without consideration of area or power. We decided to use C2MOS (Clocked CMOS) for our flip flop's, and have reached a clock speed of about 3 GHz. It seems like the inverted clock that is required for CMOS is now holding up the circuit from clocking faster. Are there any tips on how to generate an extermely fast inverted clock from the given clock? We are given a 25ps rise/fall time clock from an ideal pulse generator.
thank you, Jai.
