Advanced bipolar circuits

Advances in high-speed, low-power bipolar circuits aimed at achieving superior power-delay performance and load-driving capability over conventional ECL and NTL circuits are reviewed. The basic principles underlying power/speed improvement including 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 circuits in both n-p-n-only and complementary circuit configurations and the design tradeoffs of these circuits are discussed.<
