This paper presents a smart sensory platform based on Field Programmable Analog Array (FPAA) to support a wide variety of MEMS sensors applications. A discrete-time (DT) and continuous-time (CT) dual-mode FPAA is proposed to improve the analog signal conditioning flexibility. A gain-programmable low-noise multi-mode sensor Readout Circuit (RoC) is designed for versatile sensor weak signal acquisition,...
This paper presents a multi-mode ASIC interface with self-tuned filter to support a wide variety of MEMS gyroscope with various resonance frequencies and various output signal styles of sense/drive mode. A reconfigurable readout front-end circuit is used for signal readout in the sense channel and drive loop, which can sense the capacitive, voltage and current signal output. A gyroscope-resonance-based...
