ATE pin electronics with complementary waveform drivers

Year	Description
1999	Invention patented by Anthony E. Turvey on May 5th, 1999. Abstract: A complementary waveform driver is disclosed that generates output signals S.sub.OUT with arbitrary high and low drive states with respect to an independently controlled baseline signal S.sub.BL. Accordingly, the driver can generate very fast and flexible waveforms with multiple levels and baseline components. The driver implements complementary differential pairs of transistors that alternately source and sink programmable currents to an output port, creating an output waveform with excellent rising and falling edge symmetry, and greatly improved fidelity, especially at low level voltage swings. A complementary amplifier stage defines the baseline voltage level. When combined with a programmable active load and window comparator, the driver is particularly suited for pin electronics in automatic test equipment (ATE) applications.
