Abstract :
This paper presents an innovative conditioning and read-out interface for resistive MEMS sensor named ldquoactive-bridgerdquo. Different implementations of the proposed structure were evaluated by electrical simulations, using a 0.35mum AMS technology. The results demonstrate a significant power consumption reduction for a given SNR or a greater SNR for a given current consumption.
