Advanced bipolar circuits-a perspective

Reviews the recent advances in high-speed low-power bipolar circuits. The basic underlying principles for achieving superior power-delay performance and load driving capability, such as charge-buffering, DC/AC coupled active pull-down schemes, and complementary push-pull approaches, are examined. The utilization and combination of these basic principles to form various high-speed low-power npn-only and complementary bipolar circuit configurations are discussed.
