IP개요 | This study presents a sensor readout IC using a capacitively coupled instrumentation amplifier-embedded continuous-time delta-sigma modulator. As the frequency translation effect of chopping and the RRL have a severe side effect, we suggest practical circuit configurations to eliminate chopping artifacts, using chopping frequency as the sampling frequency. The fabricated chip is implemented in 180-nm CMOS technology, and it is able to read out both DC and AC signals. | ||
