Question

CVSL means _____________

(a) Complementary Voltage Switch Logic

(b) Cascode Voltage Switch Logic

(c) Complemented Voltage Switch Logic

(d) Cascade Voltage Switch Logic

I got this question in class test.

The origin of the question is BiCMOS Logic Circuits topic in section Logic Families of Digital Circuits

Answer 1

Right choice is (c) Complemented Voltage Switch Logic

Easy explanation: Cascode Voltage Switch Logic (CVSL) refers to a CMOS-type logic family which is designed for certain advantages. It requires mainly N-channel MOSFET transistors to implement the logic using true and complementary input signals and also needs two P-channel transistors at the top to pull one of the outputs high.
