Abstract

We have implemented a dual-modulus prescaler dividing either by 64/65 (128/129) in a 1.2 /spl mu/m standard CMOS process. Using advanced dynamic circuit techniques a maximum frequency of 1.4 GHz has been measured at a supply of 5 V and 6.9 mA. An asynchronous prescaler dividing by 16 has also been implemented. The measured maximum input frequency is 1.57 GHz at a supply of 5 V and only 3 mA.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
