Abstract
A 0.13μm CMOS four-channel analog front-end IC is presented. Each channel contains all analog and digital codec blocks, such as PGA, tuned filter, 14b ADC/DAC and digital filters. The core works with 1.5V beside the 2.5V and 3.3V interface supplies. In idle mode less than 75mW per channel is consumed.
