The sub-Watt STM-16 regenerator-section terminating digital LSI covering all functions of an STM-16 repeater, uses advanced bipolar-LSI technology. Conventional bipolar circuits are not suitable for low-power operation, because they draw a constant current and because V/sub BE/ ("on" voltage between base and emitter) is not scaled. Power-management logic for intermittently supplying a constant current, 2.5 V ECL for supply-voltage reduction, and power-optimizing CAD for minimizing total current overcome the difficulty in reducing the power of Gb/s bipolar LSIs, and enable power reduction by a factor of about 10.
