STMicroelectronics’ Powerful New FingerTip Touchscreen Technology Stifles Electrical ‘Noise’

Geneva, June 10, 2011 - STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications and the leading supplier of MEMS (Micro-Electro-Mechanical Systems) for consumer and portable applications,1 today announced its new FingerTip technology, which enables a single-chip solution for capacitive touchscreens up to 10 inches in diameter with multi-touch capability.

ST’s MEMS sensors and FingerTip technology share a similar architecture, in which a sensing element is connected to a high-performance capacitance-sensing circuit. ST has leveraged its know-how in analog and mixed-signal interface technology to develop an innovative analog-front-end that is able to detect variations of capacitance in atto-Farads (10-18 F) and to immunize the system against noise.

Touchscreen applications are subject to noise coming from various sources, including the display, the system, human touch, or battery chargers. Low-cost and poor-quality chargers, in particular, are a source of noise that can be as high as tens of volts and can affect normal operations when a finger touches the screen. When this happens, a strong periodic noise – which could be in the range of 100V (peak-to-peak) and in the frequency range from 1kHz to 1MHz – will enter into the touchscreen controller’s analog front-end and result in ‘false’ finger touches.
