A switched-R-MOSFET-C filter with tunable corner frequency is described. The tunability is achieved by varying the clock duty cycle using an automatic tuning circuit. This tuning method does not involve a change in any gate voltage , and is therefore particularly suitable for low-voltage and high-linearity applications. The advantages of the proposed method(More)
—A proposed third-order noise-shaping accelerometer interface circuit enhances the signal-to-noise ratio, compared with previously presented interface circuits. The solution for the two-chip implementation is described and a novel cross-coupled correlated double sampling integrator is proposed. This scheme functions even with large parasitic capacitances(More)
