Startup story

The story of how Silzium Circuits was founded is quite inspiring. Two friends, Dr Arun Ashok and Rijin John, with an impressive academic background and a common vision for advancing analogue radio frequency IP development in India, came up with an interesting semiconductor startup, Silzium Circuits.

Dr Arun Ashok is a Senior Researcher with Juelich Research centre, Germany and his master’s from TU Munich in Communication engineering. He has been a former research scientist at ISRO and has a PhD in RFIC design. He possesses more than 10 years of expertise in RFIC design through experiences in companies like Huawei, Infineon technologies and as a RF IC designer in RWTH Achen university.

Rijin John has been a research partner with Bell Labs India, with 8 years of experience in telecommunication and 6 years of entrepreneurial experience and protagonist in Harvard and Ivey Business Case Studies. He has is a graduate in ECE from Rajgiri school of engineering and holds a Post graduate diploma in VLSI design from NIT Calicut. It worked as a software engineer, product manager, and business analyst. He has also filed multiple patents and received strategic investments for his ventures in semiconductors.
The two friends met through their mutual interest in RF technology and decided to collaborate on creating a new IP company that would cater to the evolving requirements of the semiconductor industry globally. They named their company Silzium Circuits, which is derived from the word “silicon” and “circuit”.
