This work introduces a system formed by an integrated circuit (IC) and a micromachined piezoresistive gyroscope, with navigation grade performance. After discussing the specifications in terms of maximum allowed electronic noise, so not to worsen the thermomechanical noise limits, three different front-end topologies are analyzed, and the current-feedback instrumentation amplifier (CFIA) is chosen as the optimal solution in terms of noise and current consumption. After coupling to a gyroscope based on nanogauges, the system demonstrates 200-dps full scale,
