Analog-to-digital converter has transistors of one differential amplifier of input stage, complementary to transistors of other amplifier

摘要

The input stage of analog-to-digital converter includes differential amplifiers (DP11,DP12,DN13,DN14). First and second transistors (TP11,TP12) of at least one amplifier (DP11,DP12) are complementary to first and second transistors (TN11,TN12) of the other amplifier (DN13,DN14).
