Ph.D. Admission (Regular and Part-Time) Eligibility Criteria for the ECE Department

The following eligibility criteria are recommended by the department.


M.Tech/ME/MS(by Research) in ECE – 60% or Equivalent CPI/CGPA


B.Tech in CSE, ECE, CCE, IT, or any other equivalent discipline with a minimum of 75% or Equivalent CPI/CGPA and GATE-qualified


M.Sc (Electronics, OR, Statistics, Maths, or any equivalent discipline) with a minimum of 60% or Equivalent CPI/CGPA and GATE qualified.

The students awaiting their qualifying examination results are also eligible to apply. They need to submit the qualifying mark sheets and/or certificates at the time of admission.

Please note that the qualifying degree of applicant should be from an accredited university /deemed-to-be-university or an institution of higher learning of comparable standing. The eligibility criteria given above are the absolute minimum. Institute may prescribe any requirements over and above these. In case the candidates are awarded grades/CPI/CGPA instead of marks, applicant would have to produce the grade-percentage conversion criterion or formula provided by the university/institution from where the applicant has obtained the degree. In case, where, a university/institute does not provide any scheme for converting CPI/CGPA into equivalent marks, UGC and AICTE guidelines would be applicable.

Experience required for admission to part-time Ph.D. Programmes (Engineering):

QualificationsWork Experience (Post Qualification)
M.E./M.Tech./M.S. (by research) or equivalent1 Year
B.E./B.Tech. or equivalent3 Years

Admission Procedure

Admission to the Ph.D. Programme is offered to eligible candidates on the basis of an entrance examination and an interview. Consequently, all applicants who qualify in the written examination have to appear for the personal interview on the same day or very next day. Candidates who have qualified for national level fellowships like CSIR/UGC-NET-JRF, DST-INSPIRE, NBHM Ph.D. scholarship or equivalent valid fellowship in the relevant subject/discipline may be exempted from the written examination but not from the interview. No request for remote interviews would be entertained.


Note: DST-Inspire candidates will have two choices:

Choice 1 (Default choice): To be exempted from the written test: In this case, if finally admitted, they will not be getting any Institute fellowship and their fellowship will be subject to acceptance and approval by DST, whenever it happens. Their admission will be with fellowship status as DST-Inspire Fellowship, from the beginning.

Choice 2: NOT to be exempted from the written test: In this case, if finally admitted, they will be under Institute fellowship category until they get DST-Inspire fellowship. If they get DST-Inspire fellowship, then their fellowship status will be changed from Institute Fellowship to DST-Inspire Fellowship.

Syllabus for Ph.D. Entrance Exam

The entrance examination shall contain both objective and subjective type of questions. The syllabus for the written entrance examination shall consist of 50% of research aptitude/methodology and 50% shall be subject-specific. Research aptitude/methodology part shall be of generic nature, intended to assess the research aptitude of the candidate. This part primarily shall contain questions to test research aptitude, reasoning ability, graphical analysis, analytical and numerical ability, data interpretation, quantitative aptitude of the candidate. The subject specific syllabus is as follows:

  1. Digital Design:Number Systems & Codes, Boolean Algebra and Minimization Techniques, Digital CMOS Logic, Combinatorial Circuits & Systems, Sequential Circuits & Systems, Finite State Machines.
  2. Analog Electronics:Circuit Theorems and KCL/KVL, Op-amp, RC, RLC Circuits, Physics of transistors, Characteristics and biasing of BJT, Small signal (incremental) equivalent circuits, CE, CB and CC amplifiers, Difference Amplifier Design, Oscillators and Filters: Bode plots, Clipping, Clamping and other Non-Linear Op-Amp applications, Power supplies, DAC: Principles and Circuits, ADC: Principles and Circuits.
  3. Signals and Systems:Linear Time-Invariant (LTI) systems: Discrete and Continuous, Fourier representation of periodic signals, Fourier Transform of aperiodic signals, Laplace and z-transform, Linear Feedback Systems.
  4. Digital Signal Processing:Transform analysis of LTI systems, Structures for Discrete Time systems, FIR Filter Design Techniques, FFT, Multi-rate Digital Signal Processing, Adaptive Signal Processing, Stochastic signals, Wiener Filtering, LMS and RMS algorithms, Spectral Estimation.
  5. Basic Analog and Digital Communication:Bandwidth of AM/SSB/FM analog signals, SNR of FM system, DM/ADM/PCM, signal-to-quantization noise ratio., PSK/DPSK/QAM /OFDM systems, BER and Q-function, Error Correcting Codes: Block codes and convolutional codes
  6. Probability and Matrices Algebra:Random variables, Distributions, Mean and variance, Conditional probability, Bayes’ theorem, Correlation, Covariance, Central limit theorem, Matrix multiplication, Gaussian elimination, Determinant, Inverse of matrix, Eigenvalues and Eigenvectors, Matrix diagonalization


  1. Students may avail financial assistantship from external funding agencies (such as UGC/CSIR/NBHM/DST/DAE etc.) as well as from industries.
  2. Financial assistance is available from the Institute to the meritorious students in the form of teaching and research assistantship as per Institute norms, for those candidates who may not have any external fellowship.
  3. Partial financial support is available to the meritorious students to attend the workshops, short term courses and for paper presentation in refereed quality conferences as per Institute norms.
  4. The institute fellowship for full time Ph.D. candidates is as follows:
    • INR 31,000 per month for initial two years
