Let's Program the Transistors
This part of the Interview Question Bank deals with the general transistor level questions asked in various VLSI companies Q1. If you connect the input of an inverter to its output where will the output gets settled? Ans. The output will settle at the logical threshold of the inverter ideally at VDD/2. Q2. The Vt…

Binary coded decimal (BCD) is a way to express each of the decimal digits with a binary code. This means that each decimal digit, 0 through 9, is represented by a binary code of four bits. Eg: 98 => 10011000 Unpacking the BCD number is separating each BCD digit. Eg: 98 can be separated as 09…

This is an interview experience of Qualcomm, an American multinational semiconductor and telecommunications equipment company. This is an on campus placement experience and has been share by Mr. Anuj Kumar (BITS Pilani). Hey guys… I appeared for Qualcomm Interview from Bits-Pilani, Pilani campus. It was 2 day process which included: Written Test Written test included…
8085 is a very basic microprocessor with the capability of limited arithmetic and logical operations. It has dedicated arithmetic instructions for addition, subtraction, increment and decrement. If we want to perform a multiplication operation then we need to write a program for it. Multiplication is nothing but repeated addition. This post presents assembly language program…
Many of you might have worked on different VLSI technology nodes such as 180 nm, 90 nm, 45 nm etc. in circuit simulation tools like Cadence etc. With the invention and evolution of transistors, various technologies came into existence and more would continue to come in future. According to Moore’s law, the number of transistors…
The Electronics engineers should know the steps to design a particular circuit. While we study, we directly study the properties of the electronic block and the circuit diagram of the corresponding block. We never think how had we landed up to that particular circuit diagram. For example when we talk about digital Multiplexer, Decoder or Counters; we…
