Generation of Analog Signals for Audiometric Tests

摘要

This paper presents a dual channel fully Integrated Audiometric SYstem (LASY) which generates the complete set of audio and control signals required for exhaustive audiometric tests. The chip is fabricated in a 0.8 #mu#m CMOS process and occupies 24.2 mm~2 silicon area. It consumes 45 mW from a single 5 V power supply and achieves less than -90 dB crosstalk between thechannels.
