CMOS building block for smart-power integrated circuits

This paper describes an integrated circuit, which is suitable for use as a building block in the design of smart-power integrated circuits. The circuit comprises a logic unit and an analog section that includes zero-crossing detector, two linear-ramp generators and two voltage comparators. It produces several control pulses within the period of a sinewave input signal, allowing its use in a wide range of power-control circuits. Prototypes were implemented in 1.2 /spl mu/m n-well CMOS technology. Experimental results from measured samples are presented.
