Quick Schmitt trigger circuit

Published:2012/10/9 21:55:00 Author:Ecco | Keyword: Quick, Schmitt, trigger | From:SeekIC

Adjustment potentiometer RP in circuit can adjust T1 emitter follower so as to change the base level of T2, so the trigger level can be adjusted continuously. In the switching process, 0.6VSS control signal on diode ITT777 is applied to the T3 base. The T2 collector potential is added to the T3 base by regulator ZP. This direct coupling way can eliminate the impact of the RC link.
