Abstract :
This paper presents the technique of current mode switching in designing differential dividers for high-speed operation. Two dividers with fixed dividing ratios and a programmable divider are described to show the improvement in speed and noise performance by using current mode control and differential structure. Best performances can be obtained by optimizing parasitic. Dividers and logic gates have been designed in a modular fashion so that any dividing ratio can be obtained.
