Abstract :
Prescalers based on dynamic CMOS logic using minimum gate delays have been demonstrated as a front end for the RF synthesizers in the 1-GHz region. A speed-power product optimization method for the complementary dynamic logic has been developed and the gradual layout technique has been applied to increase the circuit yield. It is shown that it is possible to reach a 1-GHz input frequency in prescalers based on CMOS and dynamic logic only by scaling the effective channel length of the MOS transistors down to 1.1 mu m.<>
