A Research article co-authored by Dr. Anush Bekal, Associate Professor & Head-Dept. of Electronics & Communication Engineering titled - “A 13.8pJ/conv-step Binary Search ADC with Reusable Comparator Architecture” has been accepted for publication in Science Citation Index (SCI) Expanded journal; AEU - International Journal of Electronics and Communications, Elsevier having an impact factor of 3.183.
The article proposes a design of N-bit binary search (BS) Analog-to-Digital Converter (ADC) employing only ‘N/2’ comparator using double activation reusable comparator methodology. By inserting a smart switching network, the 4 comparators are getting activated twice and reused to generate the 8-bit output pattern for the proposed 8-bit ADC. In addition to this, the asynchronous mode has been adopted for activation of comparators in a sequential manner to optimize the power consumption. The proposed ADC dissipates 20.4 mW of power with a supply voltage of 1.8 V and achieves a conversion rate of 123.15 MSPS, Signal-to-Noise Ratio of 45.1 dB, Spurious-free dynamic range of 52.7 dBc, and Walden figure of merit (FOM) of 13.8 pJ/conv-step.
