World's smallest on-chip low-pass filter developed

A research team from Nanyang Technological University (NTU) in Singapore has successfully designed the world's smallest on-chip low-pass filter which 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 passing through. Compared to existing off-chip filters, which are discrete and bulky components, on-chip filters occupy a small area on integrated circuit chips, which can be found in portable devices such as mobile phones, laptops, vehicle-mounted radars, as well as speed guns used in traffic monitoring.

The successful completion of this research project was announced at the official opening of VIRTUS, the new Integrated Circuit Design Centre of Excellence, which was launched by NTU and the Economic Development Board just 10 months ago.
