High-speed differential logic multiplexer
A circuit for a high speed digital multiplexer has an active load circuit connected to an output of the digital multiplexer. The active load circuit loads the multiplexer output with a transimpedance stage with low input resistance to reduce the RC time constant at the multiplexer output. The active...

| Zusammenfassung: | A circuit for a high speed digital multiplexer has an active load circuit connected to an output of the digital multiplexer. The active load circuit loads the multiplexer output with a transimpedance stage with low input resistance to reduce the RC time constant at the multiplexer output. The active load circuit may be based on two active devices connected to the multiplexer output so as to form a differential cascode circuit. |
