NTU research team invents world’s smallest on-chip low-pass filter

Not sure if it’s just me or if NTU-related news is usually bad news. So when I saw this, I thought it’s worth sharing.

I do hope that it gets commercialised in a big way. A lot of our work ends up becoming patents that rot on shelves or gets stuck within government-linked organisations never to be heard by most people. In any case, I’m glad to hear my university(I am technically still an undergraduate there) make news for the right reasons :)

SINGAPORE: A research team from Nanyang Technological University (NTU) has a new invention that can increase the voice clarity for mobile phone users for example, even in a crowded train.

The world’s smallest on-chip low-pass filter by NTU is 1,000 times smaller than existing off-chip filters.

A low-pass filter is a circuit that allows low-frequency signals to pass through while reducing unwanted high-frequency signals from going through.

Compared to existing off-chip filters, the new invention occupies a small area on integrated circuit chips, which can be found in portable devices such as mobile phones, laptops, vehicle-mounted radars and speed guns used in traffic monitoring.

The design was unveiled this morning at the official opening of VIRTUS, the new Integrated Circuit Design Centre of Excellence.

The man behind the invention, Professor Yeo Kiat Seng, who is the Head of Circuits and Systems at NTU’s School of Electrical and Electronic Engineering, described it as a breakthrough that is set to revolutionise wireless communication.

According to Professor Yeo, the invention improves the reception and enhances clarity for users of mobile phones and other wireless applications such as Bluetooth and other mobile devices.

“If you are speaking to your friend on your mobile phone in a noisy food centre or in a train, you would still be able to hear him clearly,” said Professor Yeo.

The filter also consumes less power and can be incorporated into existing IC chips at almost no cost.

This filter project is jointly funded by NTU and Exploit Technologies Pte Ltd, the marketing and commercialisation arm of the Agency for Science, Technology and Research (A*STAR).

Six industry players, including companies such as Infineon Technologies and Mediatek Inc, have pledged to contribute S$5.5 million to VIRTUS to support advanced integrated circuit design research.
