Abstract :
A simple numerical procedure is introduced to allow straight-forward design of high speed, resistor loaded, differential amplifiers in modern CMOS processes whose device characteristics dramatically depart from traditional square law characteristics. The analytical form of the procedure allows for an intuitive perspective of the varying gain-bandwidth product for such amplifiers. Calculations based on the method are compared to Hspice simulated results based on a 0.18 μm CMOS process. Its application to the design of high speed, source-coupled logic (SCL) gates and latches are also discussed.
