Title: Method and apparatus for reducing output noise in digitally rebalanced accelerometer
Inventor: TAZARTES DANIEL A
IPC: H03M1/50
Filed: 2000-07-28
Abstract: PROBLEM TO BE SOLVED: To reduce a periodic low frequency noise of an output of an accelerometer by maintaining a pendulum-like mass at a zero position by using a rebalance loop. SOLUTION: In this accelerometer, plates 12, 14 form capacitors C1, C2 together with a pendulum-like mass 10, and are connected to a parallel feedback route of an arithmetic amplifier 16. Switches S1, S2 on the route are alternately turned ON according to a timing signal of a state machine 22. When the switch is turned ON, a voltage pulse 20 supplied to the amplifier 16 alternately generates a charge at the plate 12, 14. A differential sample and hold circuit 24 standardizes the voltages of both the plates, measures a difference between the voltages, and sends it to an arithmetic amplifier 28. An analog signal indicating a force for maintaining the mass 10 of the amplifier 28 '0' is compared with an output of a chopping wave generator 36, and triggers an FF 40.  The FF 40 takes timing for supplying a using ratio of the rebalance in response to a pick-off signal to the plats 12, 14 by its output, and sets a position of the mass 10 to '0'.
