Abstract :
A cascadable 4-bit synchronous counter is presented which has been fabricated with a conventional Si bipolar technology featuring 2-μm emitter stripe width and no self-alignment process steps. It can be operated in the count-up, parallel-data-load, and stop-counting modes up to 2.1 GHz. The high operating speed was made possible by careful transistor and circuit optimization
