摘要： A transconductance-capacitance (Gm-C) filter of arbitrary order is provided that is biased by a bias circuit such that the Gm-C filter is robust to variations in process corner and temperature as well as input supply noise. The bias circuit includes a biased transistor that has a width-to-length ratio that is a factor X times larger than a corresponding transistor in the Gm-C filter. The biased transistor couples to ground through a switched capacitor circuit.

摘要： A tunneling accelerometer includes a proof mass that moves laterally with respect to a cap wafer. Either the proof mass or the cap wafer includes a plurality of tunneling tips such that the remaining one of proof mass and the cap wafer includes a corresponding plurality of counter electrodes. The tunneling current flowing between the tunneling tips and the counter electrodes will thus vary as the proof mass laterally displaces in response to an applied acceleration.
