Complementary output generator module

Abstract

A complementary output generator (COG) module generates at least two complementary outputs determined by rising and falling event sources. In a simple configuration of the COG module, the rising and falling event sources are the same signal which is a signal having the desired period and duty cycle. The COG module converts this single signal input into dual complementary outputs. The frequency and duty cycle of the dual outputs substantially match those of the single input signal. Blanking and deadband times may be introduced between the complementary outputs, and the dual complementary outputs may also be phase delayed. In addition the COG module may provide up to four outputs for controlling half and full-wave bridge power applications.
