Welcome to Imran Ahmed's Data Connection (IADC)! I completed my PhD in the Department of Electrical and Computer Engineering at the University of Toronto, under the supervision of Professor David A. Johns. I was with the Electronics Group working on mixed signal research. I co-founded Kapik Integration, a Toronto area start-up whose expertise is enabling next generation technologies with 'smart analog' approaches.

My Masters and Doctorial research was focused on various aspects of pipeline ADCs. For my Master's work I developed a 10-bit power scaleable ADC which was able to have its power scale from 1kS/s (15uW) to 50MS/s (35mW). My PhD research was aimed at developing advanced calibration schemes for pipeline ADCs, developing circuit techniques to reduce ADC power for sub-sampling applications, and developing very low power pipelined ADC architectures. At Kapik I have been involved on a variety of different mixed-signal circuits from low speed sensor interfaces to high speed data communication.

I am also author of a book 'Pipelined ADC Design and Enhancement Techniques' (Springer 2010). The book provides a general overview of pipelined ADC design as well as a detailed discussion of several state-of-the-art implementations.
