N-trig attains success in mass production using custom ASIC from Cosmic Circuits

BANGALORE, INDIA & CAMPBELL, USA: Cosmic Circuits, a leading provider of Analog and Mixed Signal ASICs, announced that N-trig providers of DuoSense® a pen and projected capacitive multi-touch solution enabled over a single digitizer has now implemented into mass production a custom ASIC having high performance analog circuits.

Cosmic Circuits has a broad IP portfolio that forms the foundation for the ASIC platform. Typically ASIC design begins with a high level requirement from the customer followed by development of detailed specification which Cosmic develops along with the customer.

Cosmic Circuits has strong partnerships with foundry, test development and packaging and assembly vendors to ensure the delivery of a complete turnkey solution to the customer with definite lead times and fixed costs.

The custom ASIC drew on Cosmic’s expertise in various analog domains, it helped realize a chip with various modules such as preamplifiers for sensor interface followed by Analog to Digital converter, several low power Charge Pump modules to power different sections of the chip, and a 20v charge pump . The ASIC which works of a single 1.5V battery can operate over a 0.9V to 1.5V range.

Yaki Luzon, VP and GM, N-trig APAC, said: “We required an analog IC partner who could effectively complement our innovations in systems and digital media. We chose Cosmic as they have a broad level of understanding and expertise in analog technology, and a particular focus on realizing differentiated analog designs. N-trig and Cosmic have an ongoing collaborative cooperation, and we are confident that the relationship will grow, having seen how Cosmic delivers on their commitments in realizing innovative and novel custom silicon solutions.”

Sumeet Mathur, director of Analog ASIC of Cosmic Circuits, commented: “The low power and high voltage aspects were the biggest challenges in ensuring timely completion of IC qualification. Making the right choices at architecture level and then keeping a very tight control on the test and qualification steps enabled us in achieving production readiness in a relatively short time from first
