Abstract: Systems and methods for insuring successful initiation of a resonating micro-electro mechanical systems (MEMS). An example system (20) includes a resonating sensor (24), a drive device (26), a charge amplifier, and a voltage gain circuit (28). At start up, the charge amplifier and voltage gain circuit receives signals from the resonating sensor, compensates this signal for DC offsets, and generates a clock signal for the drive, thus placing the resonating sensor in a steady state operating mode. The circuit includes a plurality of switches that are toggled to produce a glitch in the signal associated with the received signal. The glitch overcomes the DC offset. A comparator generates the clock signal for the drive device if a signal associated with the received signal exceeds a reference signal.

Abstract: In a circuit (1) for producing or transmitting control signals (Q) for a current inverter (2) comprising at least one first switch (Shigh) with a high potential and a second switch (Slow) with a low potential, a connection point between the two switches (Shigh, Slow) forms the output of the current inverter (2). The circuit (1) also comprises a capacitor (Ccap) which a) is connected to the output of the current inverter (2) in a first operating phase by means of switching elements (S1-S4), in such a way that it enables a current flow in a state wherein the two switches (Shigh/ Slow) of the current inverter (2) are open, and b) is connected to the current inverter output in a second operating phase by means of the switching elements (S1-S4) with high impedance, such that a control signal (Q) applied to a side of the capacitor (Ccap) by a control device is transformed into a higher potential.

Abstract: A low power consumption shift register which inputs a CK signal with a low voltage with almost no effect of variation in characteristics of transistors. In the invention, an input portion of an inverter is set at a threshold voltage thereof and a CK signal is inputted to the input portion of the inverter through a capacitor means. In this manner, the CK signal is amplified, which is sent to the shift register. That is, by obtaining the threshold potential of the inverter, the shift register which operates with almost no effect of variation in characteristics of transistors can be provided.
