A new fully-analog integrated lock-in amplifier for the accurate detection and measurement of noisy physical/chemical phenomena in sensor applications is here presented. The proposed system, implemented as a single-chip in a 0.35μm standard CMOS technology, performs an automatic alignment of the relative phase between input and reference signals as well as a self-tuning, at the reference operating frequency, both at power-on and for any variation during its working time, so allowing to reveal… CONTINUE READING
