Question

The process to avoid saturating the switching transistor is performed by ___________

(a) Baker clamp

(b) James R. Biard

(c) Chris Brown

(d) Totem-Pole

This question was posed to me in an interview for internship.

I want to ask this question from Diode-Transistor Logic(DTL) in chapter Logic Families of Digital Circuits

Answer 1

The correct choice is (a) Baker clamp

To explain I would say: Another way to speed up DTL other than adding a small “speed-up” capacitor across intermediate resister is to avoid saturating the switching transistor which can be done with a Baker clamp. The name Baker clamp is given at the name of Richard H. Baker, who described it in his 1956 technical report “Maximum Efficiency Switching Circuits”.
