Ultra-low ESR capacitors such as ceramics are highly desirable because they can support fast-changing load transients and also bypass very high frequency noise coming from switching converter power sources, which a linear regulator can not reject. However, using ultra-low ESR capacitors on the output of an LDO regulator requires that specific design changes be implemented to ensure loop stability.

Experimental validation in addition to detailed modeling and simulation of a new transformer-less series compensator for linecommutated HVDC rectifier terminal is presented. The compensator employs very small capacitors compared to those in conventional shunt compensators or fixed series capacitors for reactive power compensation of such links.

A novel and efficient approach to realize fractional-order capacitors is investigated in this paper. Meanwhile, a new approach which is more efficient for semiconductor implementation of fractional-order capacitors is proposed. The feasibility of the approach has been verified with the preliminary measured results. Keywords—Fractional-order, field-effect transistors, RC transmission lines.

A new voltage-mode multifunction biquadratic filter using one differential difference current conveyor (DDCC), two grounded capacitors and three resistors is presented.

We have studied the reliability of intrinsic SiN MIM capacitors designed for 48 V and 125 0 C operation and manufactured in a GaN process flow. It is shown that very small area capacitors (10um x 10um) with a dielectric thickness of 400nm exhibit lifetimes as long as 1.48E10 hours under such conditions.

Novel common-mode feedback circuits are proposed for use in pseudo-differential switched-capacitor circuits. They can be implemented by incorporating just four additional capacitors (and switches) for an integrator, and only two additional capacitors for a residue gain amplifier. The circuits are applicable to very low-voltage switched-capacitor stages realized in submicron low-voltage CMOS pro...

We present ramped voltage data from a new nitride used in our fabrication process. Using the same fabrication flow, we measured increased lifetimes for capacitors using this new dielectric. Using the linear field model, this translates into capacitors that can sustain higher applied voltages before they fail.
