Why stay in UK？ Why choose our company?
They asked me to recall a few specific details regarding a project I had completed several years back.
Draw and explain the inner workings of a buck regulator?
Have you used FPGA ?
CMOS logic for an NAND gate? Will the logic change if the input has different delays? MOSFET regions and current equation? Internal circuit of D flip flop? What is hold time and setup time?
Round 1 - • Section 1 – Aptitude and Logical reasoning questions with some basic math. • Section 2 – C language based coding MCQs including pointers, arrays, and etc. and general number system questions. • Section 3 – Digital Electronics section with questions from Combinational and Sequential circuits, Boolean algebra, CMOS, BJT, ADC and DAC, etc. Round 2 - • A few questions about my resume. • Draw transfer characteristics of inverter. • What is the threshold voltage of an inverter? • What is high and low Noise margin? What does it signify • Draw CMOS inverter and mark all 4 terminals. • Draw a physical diagram of an NMOS. • What happens if the body is not shorted to source? What might happen if it is connected to a higher voltage than source? • What are state machines? • Write the Verilog code for a mod-3 counter. • What are the common mistakes one can make while writing this Verilog code? • How would you make an AND gate with a 2x1 MUX? • How would you make an OR gate with an XOR gate? Round 3 - • Asked a few general personal questions about me and resume. • A logical aptitude based question – If you have 2 cubes with 6 surfaces each, how will you any day of a month from 01 to 31 using the 2 cubes by writing any single digit number on each side of both the cube? • Implement an OR gate using NAND gates. • Draw an OR gate using a 2x1 MUX. • What is the equation of an EXOR gate? • Draw a NAND gate using CMOS logic. • Explain how it functions. • What is setup time and hold time? • What are the different types of Finite state machines? What is the difference? • Draw the state diagram of a sequence detector to detect - 01*0010*1 - where 1* means that 1 can be repeated any number of times and similarly 0*. • Verbally explain how you would write a Verilog code for a finite state machine. • Discussions regarding job location.
