Description: School of Electronics and Communication Engineering, Team 3 organized webinar session on “Design of Low power Trans-conductor capacitor (Gm-C) based continuous time filter” on 12-09-2020 at 3:00 PM to 4:00PM. The resource person was Dr Vasanth M H and more than 30 participants including students, Faculties and research scholars have attended the session. 
Dr Vasanth M H, is holding the post of Registrar, NIT Goa since May 2017. He has completed B.Tech.  from Mangalore University and received the Masters of engineering degree in Electronics and  Communication from the IIT Madras, India, and Doctor of Philosophy from the Department of Electronics and Communication from the NIT Surathkal, India. He has served as HoD of  ECE Department, NIT Goa from 2015 to 2018. He is at present serving as Associate Professor in the department Electronics and Communication Engineering, NIT Goa, India. His research interests are on Low voltage Microelectronics Low power analog and digital circuits, Continuous-time filter Circuits, System on Chip, fault-tolerant and networks-on-chip and embedded systems, Approximate computations. He has published research articles more than 25 conferences and 15 Journals and is also having 2 transaction papers.
In a typical system on-chip (SoC), analog and RF front end exist along with the digital circuit and integrated to consume power efficiently. Unlike digital design, where the trade-off is mainly on two parameters such as speed and power, the analog design has multidimensional design trade-offs. Tuning to these trade-offs is challenging at low voltage. This poses a huge demand for low-voltage analog circuit design in standard digital CMOS technology. The bulk-driven technique for realizing trans-conductors for low voltage applications operating on 0.5 V supply. The Trans-conductor- Capacitor (Gm-C) continuous time filter is designed using 0.5V power supply based on standard cascade of biquad architecture. The filter bandwidth is limited by the realizable gain- bandwidth of the operational transconductance amplifier (OTA) for the given power. If, the dynamic range requirement is relaxed, Gm-C filters can be designed to offer higher bandwidth for the same power.

The key highlights of the session were:
•    Technology scaling
•    Effect of voltage scaling on analog domain
•    OTA(Gm)-C filter: Details
•    Case Study: - Design of 4th order Gm-C based LP filter
