In this paper a low-power current-mode RMS-to-DC converter is proposed. The proposed converter includes absolute value circuit, squarer/divider circuit, low-pass filter and square root circuit which employ CMOS transistors operating in weak inversion region.

This paper presents the design and a new low-cost process for fabrication of a second-order micromechanical filter using UV-LIGA technology. The micromechanical filter consists of two identical bulk-mode ring resonators, mechanically coupled by a flexural-mode beam. A new lumped modeling approach is presented for the bulk-mode ring resonators and filter. The validity of the analytical derivatio...

In the field of analog signal processing, there is a strong need for low-voltage and low-power integrated circuits. Especially in the mobile communication circuitry, an analog signal processing circuit must be fed by dry batteries of 1–1.5 V.

An on-chip process, supply voltage, and temperature (PVT) compensation technique for low-voltage CMOS digital circuits was proposed. Because the degradation of circuit performance originates from the variation of the saturation current in transistors, we developed a compensation circuit consisting of a reference current that is independent of PVT variations. The circuit is operated so that the ...
