INTEGRATED CIRCUIT SWITCHING NETWORK PROVIDING CROSSPOINT GAIN

An integrated circuit thyristor switching network in which a parasitic pnp transistor effect, normally encountered as a result of the junction isolation employed, provides a crosspoint gain rather than the loss previously presented by the thyristor. When a thyristor crosspoint is switched to its on...

Zusammenfassung:An integrated circuit thyristor switching network in which a parasitic pnp transistor effect, normally encountered as a result of the junction isolation employed, provides a crosspoint gain rather than the loss previously presented by the thyristor. When a thyristor crosspoint is switched to its on state, the effective pnp transistor is biased to its active region and draws current from the negatively biased substrate to augment the signals being applied to a selected network path.
