The way to speed up DTL is to add an across intermediate resister is ___________(a) Small “speed-up” capacitor(b) Large “speed-up” capacitor(c) Small “speed-up” transistor(d) Large ” speed-up” transistorI got this question in an internship interview.Question is from Diode-Transistor Logic(DTL) topic in chapter Logic Families of Digital Circuits

Answer»

Right option is (a) Small “SPEED-up” capacitor

To elaborate: ONE WAY to speed up DTL is to add a small “speed-up” capacitor across intermediate resister. The capacitor helps to turn off the transistor by removing the stored base charge; the capacitor also helps to turn on the transistor by increasing the INITIAL base DRIVE.
