Design of Digital Baseband Transceiver for Touchscreen Devices
MetadataShow full item record
With recent advances in low power electronics combined increasingly smaller integrated circuits, battery-driven smart devices are becoming more prevalent. The thesis motivation is proposed by Atmel,Norway to develop a digital baseband transceiver architecture which can be implemented to handle digital communications between an active stylus and a hand-held, touchscreen devices.This thesis presents a baseband digital transceiver architecture including transmitter andreceiver. the focus of the design is on the receiver architecture. The transceiver design exploited a one bit architecture. The baseband modulation implemented direct sequence spread-spectrum communication modulation which proved effectiveness in simulations. The hardwareimplantation was done in simple hardware architecture using hardware description languageSystemVerilog.
