The design and performance of a miniaturized coplanar capacitive sensor is presented whose electrode arrays can also function as resistive microheaters for thermocapillary actuation of liquid films and droplets. Optimal compromise between large capacitive signal and high spatial resolution is obtained for electrode widths comparable to the liquid film thickness measured, in agreement with suppo...

A novel smart resistive-capacitive angular position sensor is presented. The main advantages of this low-cost system are its simplicity, high stability and high reliability. A very hear oscillator is used in the processing circuit to convert the position quantity to a period-modulated signal which can directly be read out by a microcontroller. The system does not need an A/D converter. The nonl...

Introduction: The class-AB buffer amplifier is widely used for driving heavy resistive or capacitive loads [1–4]. Some buffer amplifiers employ a pseudo-source follower, which has a pair of complementary common-source transistors with two feedback loops consisting of a pair of complementary error amplifiers [1–2]. Employing error amplifiers introduces the excess phase shift and makes the freque...

A current-mode implementation of a frequency-dependent negative resistance (FDNR) element is presented using a novel capacitive gyrator. This FDNR element lends itself well to the design of low-pass ladder filters and its use will result in a more efficient integrated circuit implementation than filters that simulate floating inductors using resistive gyrators.

Resistive Random Access Memories based on metal-oxide polymer diodes are characterized. The dynamic behavior is studied by recording currentvoltage characteristics with varying voltage ramp speed. It is demonstrated that these organic memory devices have an internal capacitive double-layer structure, which inhibits the switching at high ramp rates (1000 V/s). This behavior is modeled and explai...

A current mirror (CM) based on self cascode arrangement, useful for low voltage analog and mixed mode circuit is proposed.
